[0036] Based on the above technical solution, the embodiment of the utility model has at least the following advantages and positive effects:
[0037] In the steam generator of the embodiment of the utility model, a first heating chamber and a steam chamber arranged above are provided in the shell. External water can be introduced into the first heating chamber through the water inlet, and the first heating chamber is heated by the heating element, so that the steam of the first heating chamber can enter the steam chamber upward, and then be discharged from the shell through the steam outlet to supply pure steam to the outside.

[0039] Figure 1 It is a structural schematic diagram of a steam generator according to an embodiment of the utility model. Figure 2 yes Figure 1 Front view of . Figure 3 yes Figure 1 Top view of the . Figure 4 yes Figure 3 AA section view.
[0040] See also Figures 1 to 4 As shown, the steam generator provided by the embodiment of the utility model may include a shell 1. The shell 1 can be used as an outer shell of the steam generator. The inside of the shell 1 is hollow, and the inside of the shell 1 can be used to heat water to form steam.
[0041] In some embodiments, a water inlet 101 may be provided on the outer wall of the housing 1. External water may enter the housing 1 through the water inlet 101 and form steam after being heated.
[0042] In some embodiments, a water inlet valve (not shown) may be connected to the water inlet 101 of the housing 1. The water inlet valve may control the opening and closing of the water inlet 101. When the water inlet valve is opened, external water may enter the housing 1 through the water inlet 101. When the water inlet valve is closed, water from the water inlet 101 stops entering the housing 1.
[0043] See also Figures 1 to 4 As shown, in some embodiments, a water inlet pipe 121 may be protruded from the outer wall of the housing 1. The water inlet 101 may be formed in the water inlet pipe 121. The water inlet valve may be connected to the water inlet pipe 121.
[0044] In some embodiments, the water inlet pipe 121 may be arranged to extend upward from the top wall of the housing 1, so that the water inlet 101 may be arranged to extend upward from the top wall of the housing 1. External water may flow downwardly into the housing 1 along the water inlet 101.
[0045] It should be noted that, in some other embodiments, the water inlet pipe 121 may also be arranged on other side walls of the shell 1 , that is, the water inlet 101 may also be arranged on other outer walls of the shell 1 .
[0046] See also Figures 1 to 4 As shown, in some embodiments, the steam generator may include a heating element 2. The heating element 2 may extend into the housing 1. When the heating element 2 is working, the water inside the housing 1 may be heated, thereby forming steam from the water.
[0047] In some embodiments, the heating element 2 may be a heating tube, and the heating tube may be extended into the housing 1. It should be noted that in other embodiments, the heating element 2 may also be other heating devices such as a heating wire.
[0048] See also Figures 1 to 4 As shown, in some embodiments, a steam outlet 102 may be provided on the outer wall of the housing 1. The steam generated by heating inside the housing 1 may be discharged to the outside of the housing 1 through the steam outlet 102, thereby providing steam to the outside.
[0049] In some embodiments, a steam pipe 122 may be protruded from the outer wall of the housing 1 , and the steam outlet 102 may be formed in the steam pipe 122 .
[0050] In some embodiments, the steam pipe 122 can be connected to a steam nozzle (not shown) through a pipeline, so that the steam formed in the shell 1 is transported to the steam nozzle through the pipeline, and steam is provided to the outside through the steam nozzle.
[0051] In some embodiments, the steam pipe 122 may be arranged to extend upward from the top wall of the shell 1, so that the steam outlet 102 may be arranged to extend upward from the top wall of the shell 1. When the steam formed inside the shell 1 is ejected from the steam pipe 122, the condensed water formed on the inner wall of the steam pipe 122 may flow downward along the inner wall of the steam pipe 122 and then fall back into the shell 1.
[0052] It should be noted that, in some other embodiments, the steam pipe 122 may also be arranged on other side walls of the shell 1 , that is, the steam outlet 102 may also be arranged on other outer walls of the shell 1 .
[0053] See also Figures 1 to 4 As shown, in some embodiments, a first heating chamber 110 may be provided in the housing 1. A water inlet 101 may be arranged above the first heating chamber 110. The water inlet 101 may be in communication with the interior of the first heating chamber 110. The heating element 2 may be arranged in the inner wall of the first heating chamber 110. External water may enter the first heating chamber 110 through the water inlet 101 and be heated by the heating element 2 to form steam. The steam formed in the first heating chamber 110 may be discharged to the outside of the housing 1 through the steam outlet 102.
[0054] See also Figure 4 As shown, in some embodiments, a steam chamber 140 may be provided in the housing 1. The steam chamber 140 may be separated from the first heating chamber 110 up and down. The steam chamber 140 may be arranged above the first heating chamber 110. The top area of the first heating chamber 110 may be communicated with the top area of the steam chamber 140. The steam outlet 102 may be arranged in the top area of the steam chamber 140, and the steam outlet 102 may be communicated with the inside of the steam chamber 140. The steam formed in the first heating chamber 110 may flow from the top area of the first heating chamber 110 to the bottom area of the steam chamber 140, and then enter the steam chamber 140, and then be discharged from the housing 1 through the steam outlet 102.
[0055] It should be noted that, since the water inlet 101 is not directly connected to the steam chamber 140, the steam chamber 140 is separated from the first heating chamber 110 from top to bottom. When external water enters the first heating chamber 110 through the water inlet 101, the water in the first heating chamber 110 will not splash into the steam chamber 140, so the water will not directly enter the steam chamber 140. Only the steam formed after heating in the first heating chamber 110 can enter the steam chamber 140 and be discharged from the housing 1 from the steam outlet 102, so the problem of water spraying when the steam is sprayed can be effectively avoided.
[0056] See also Figure 4As shown, in some embodiments, a second heating chamber 120 may be provided in the housing 1. The second heating chamber 120 may be arranged to be separated from the first heating chamber 110 in a transverse manner. The top area of the first heating chamber 110 may be connected to the top area of the second heating chamber 120. Therefore, external water may directly enter the first heating chamber 110 through the water inlet 101, and may not directly enter the second heating chamber 120. The water in the first heating chamber 110 may overflow and enter the second heating chamber 120, so the water in the first heating chamber 110 is usually more than the water in the first heating chamber 110.
[0057] In some embodiments, the heating element 2 can be arranged in the inner wall of the first heating chamber 110 and the second heating chamber 120 at the same time. The heating element 2 can heat the first heating chamber 110 and the second heating chamber 120 at the same time, so that the water in the first heating chamber 110 and the water in the second heating chamber 120 can be heated to form steam.
[0058] It should be noted that, in other embodiments, a plurality of heating elements 2 may be provided, and the plurality of heating elements 2 may be respectively arranged in the inner walls of the first heating chamber 110 and the second heating chamber 120. The plurality of heating elements 2 may heat the water in the first heating chamber 110 and the second heating chamber 120, respectively.
[0059] In some embodiments, the amount of water inflow at a time can be controlled so that the first heating chamber 110 overflows into the second heating chamber 120 after being full, thereby allowing water to be present in both the first heating chamber 110 and the second heating chamber 120. The heating element 2 is used to heat the first heating chamber 110 and the second heating chamber 120 simultaneously, thereby allowing the water in the first heating chamber 110 and the water in the second heating chamber 120 to be heated to form steam, thereby improving the efficiency of steam formation.
[0060] See also Figure 4 As shown, in some embodiments, the steam chamber 140 can be arranged above the second heating chamber 120, that is, the second heating chamber 120 can be located below the bottom of the steam chamber 140. The top area of the second heating chamber 120 can be connected to the bottom area of the steam chamber 140. Therefore, when the heating element 2 is heated, the water in the first heating chamber 110 and the second heating chamber 120 can be heated to form steam. The steam in the first heating chamber 110 can enter the top area of the second heating chamber 120 from the top area of the first heating chamber 110, merge with the steam formed in the second heating chamber 120, and enter the steam chamber 140 from the top area of the second heating chamber 120.
[0061] It should be noted that, as the water level in the second heating chamber 120 decreases, the water in the second heating chamber 120 is less likely to splash into the steam chamber 140 when it is heated and boiled. Therefore, the water level in the second heating chamber 120 can be controlled by controlling the single water inflow amount to prevent boiling water from splashing into the second heating chamber 120, so that the steam in the second heating chamber 120 entering the steam chamber 140 is pure steam, thereby effectively avoiding the problem of water spraying when the steam outlet 102 sprays steam.
[0062] See also Figure 4 As shown, in some embodiments, a partition 3 may be provided between the top of the second heating chamber 120 and the bottom of the steam chamber 140, and the partition 3 may separate the internal space of the housing 1 into upper and lower parts. The second heating chamber 120 may be formed below the partition 3. The steam chamber 140 may be formed below the partition 3. A steam hole 31 may be provided on the partition 3. The steam hole 31 may be located above the top of the second heating chamber 120. The top area of the second heating chamber 120 may be connected to the bottom area of the steam chamber 140 through the steam hole 31. Therefore, the steam in the second heating chamber 120 can enter the steam chamber 140 through the steam hole 31. Condensate generated after the steam in the steam chamber 140 is condensed can drip from the steam hole 31 into the second heating chamber 120, and after being reheated by the steam, it enters the steam chamber 140 through the steam hole 31.
[0063] See also Figure 4 As shown, in some embodiments, a third heating chamber 130 may be provided inside the housing 1. The third heating chamber 130 may be provided between the first heating chamber 110 and the second heating chamber 120. The first heating chamber 110, the third heating chamber 130 and the second heating chamber 120 may be arranged in a transverse manner and separated in sequence. The top areas of the first heating chamber 110, the third heating chamber 130 and the second heating chamber 120 may be connected in sequence. After external water enters the housing 1 through the water inlet 101, the first heating chamber 110 may be filled up first. After the first heating chamber 110 is filled up with water, the water in the first heating chamber 110 may overflow into the third heating chamber 130. When the third heating chamber 130 is filled up with water, the water in the third heating chamber 130 may overflow into the second heating chamber 120.
[0064] Therefore, by controlling the single water inflow, water can be stored in the first heating chamber 110, the third heating chamber 130, and the second heating chamber 120 at the same time. By heating the first heating chamber 110, the third heating chamber 130, and the second heating chamber 120 at the same time, the steam formed in the first heating chamber 110 can enter the third heating chamber 130, and after merging with the steam formed in the third heating chamber 130, it can enter the second heating chamber 120, thereby improving the steam formation efficiency and increasing the steam amount in the second heating chamber 120.
[0065] In some embodiments, the heating element 2 can be arranged in the inner walls of the first heating chamber 110, the third heating chamber 130 and the second heating chamber 120 at the same time, so that the water in the first heating chamber 110, the third heating chamber 130 and the second heating chamber 120 can be heated simultaneously by the heating element 2.
[0066] It should be noted that, in other embodiments, a plurality of heating elements 2 may be provided, and the plurality of heating elements 2 may be respectively arranged in the inner walls of the first heating chamber 110, the third heating chamber 130, and the second heating chamber 120. The plurality of heating elements 2 may heat the water in the first heating chamber 110, the third heating chamber 130, and the second heating chamber 120, respectively.

[0068] See also Figures 4 to 6 As shown, in some embodiments, a first baffle 111 may be provided in the housing 1. The first baffle 111 may be arranged between the first heating chamber 110 and the third heating chamber 130. The first heating chamber 110 and the third heating chamber 130 may be formed on opposite sides of the first baffle 111, respectively.
[0069] In some embodiments, a first overflow port 112 may be provided at the top of the first baffle 111 to connect the first heating chamber 110 and the third heating chamber 130. The first overflow port 112 may be arranged at the top area of the first heating chamber 110 and the third heating chamber 130. When the first heating chamber 110 is full of water, the water overflowing from the first heating chamber 110 can enter the third heating chamber 130 through the first overflow port 112. When the heating element 2 is working, the steam formed in the first heating chamber 110 can enter the third heating chamber 130 through the first overflow port 112.
[0070] See also Figures 4 to 6 As shown, in some embodiments, a second baffle 113 may be provided in the housing 1. The second baffle 113 may be arranged between the second heating chamber 120 and the third heating chamber 130. The second heating chamber 120 and the third heating chamber 130 may be formed on opposite sides of the second baffle 113, respectively.
[0071] In some embodiments, a second overflow port 114 connecting the second heating chamber 120 and the third heating chamber 130 may be provided at the top of the second baffle 113. The second overflow port 114 may be arranged at the top area of the second heating chamber 120 and the third heating chamber 130. When the third heating chamber 130 is filled with water, the water overflowing from the third heating chamber 130 can enter the second heating chamber 120 through the second overflow port 114. When the heating element 2 is working, the steam in the third heating chamber 130 can enter the second heating chamber 120 through the second overflow port 114.
[0072] See also Figures 4 to 6 As shown, in some embodiments, a plurality of third heating chambers 130 may be provided in the housing 1. The plurality of third heating chambers 130 may be arranged between the first heating chamber 110 and the second heating chamber 120. The plurality of third heating chambers 130 are arranged in sequence, and the top areas of the plurality of third heating chambers 130 may be connected in sequence, and then the top areas of the first heating chamber 110, the plurality of third heating chambers 130, and the second heating chamber 120 may be connected in sequence.
[0073] When the first heating chamber 110 is full of water, the water overflowing from the first heating chamber 110 can enter the adjacent third heating chamber 130. When the third heating chamber 130 is full of water, the water can overflow into the adjacent next third heating chamber 130. By controlling the single water inflow, the water in the third heating chamber 130 can overflow and finally enter the second heating chamber 120, so that the first heating chamber 110, the plurality of third heating chambers 130 and the second heating chamber 120 are all filled with water.
[0074] When the heating element 2 is working, the steam formed in the first heating chamber 110 can enter the third heating chamber 130, and then enter the second heating chamber 120, and enter the steam chamber 140 through the top area of the second heating chamber 120. The first heating chamber 110, the third heating chambers 130, and the second heating chamber 120 can be heated at multiple stages to improve the steam formation efficiency and prevent water from directly entering the steam chamber 140, thereby solving the water spray problem when the steam is sprayed out from the steam outlet 102.
[0075] It should be noted that, in some embodiments, the number of the third heating chambers 130 can be set as needed and is not limited here.
[0076] In some embodiments, a third baffle (not shown) may be provided between adjacent third heating chambers 130. Two adjacent third heating chambers 130 may be formed on opposite sides of the third baffle, respectively. A third overflow port is provided at the top of the third baffle, which communicates with the top areas of the two adjacent third heating chambers 130.

[0084] See also Figures 4 to 11As shown, in some embodiments, the housing 1 may include an upper cover 12. The upper cover 12 may be disposed on the top of the heating base 11. The steam chamber 140 may be formed inside the upper cover 12. When the upper cover 12 is on the top of the heating base 11, the first heating chamber 110, the third heating chamber 130, and the second heating chamber 120 may be formed between the bottom of the upper cover 12 and the inside of the heating base 11, respectively.
[0085] In some embodiments, the upper cover 12 is detachably arranged on the top of the heating base 11. It should be noted that, in other embodiments, the upper cover 12 can also be integrally formed on the top of the heating base 11.
[0086] See also Figures 4 to 11 As shown, in some embodiments, the partition 3 can be disposed between the bottom of the upper cover 12 and the top of the heating base 11. When the upper cover 12 is on the top of the heating base 11, the partition 3 can be sandwiched between the bottom of the upper cover 12 and the top of the heating base 11.
[0087] In some embodiments, the partition 3 can be detachably disposed between the bottom of the upper cover 12 and the top of the heating base 11. In other embodiments, the partition 3 can also be integrally formed at the bottom of the upper cover 12, or the partition 3 can also be integrally formed at the top of the heating base 11.
[0088] See also Figures 4 to 11 As shown, in some embodiments, the partition plate 3 is detachably fixed to the bottom surface of the upper cover 12. The partition plate 3 is detachably covered at the bottom opening of the steam chamber 140.
[0089] See also Figures 4 to 11 As shown, in some embodiments, the water inlet pipe 121 and the water inlet 101 can be arranged on the top wall of the upper cover 12. The water inlet pipe 121 and the water inlet 101 can be extended upward from the top wall of the upper cover 12.
[0090] It should be noted that, in other embodiments, the water inlet pipe 121 and the water inlet 101 may also be disposed on the side wall of the upper cover 12 .
[0091] See also Figures 4 to 11 As shown, in some embodiments, a water inlet groove 123 may be recessed on the bottom surface of the upper cover 12. The water inlet 101 is connected to the water inlet groove 123 vertically. When the upper cover 12 is placed on the heating base 11, the water inlet groove 123 is connected to the first heating chamber 110 vertically. Therefore, when the external water source enters the housing 1 through the water inlet 101, it can fall into the first heating chamber 110 below through the water inlet groove 123.
[0092] See also Figures 4 to 11As shown, in some embodiments, the steam pipe 122 can be arranged to extend upward from the top wall of the upper cover 12, so that the steam outlet 102 can be arranged to extend upward from the top wall of the upper cover 12. When the steam in the steam chamber 140 is ejected from the steam pipe 122, the condensed water formed on the inner wall of the steam pipe 122 can flow downward along the inner wall of the steam pipe 122, and then fall back into the steam chamber 140, and together with the condensed water on the inner wall of the steam chamber 140, fall back from the steam hole 31 into the second heating chamber 120, and be reheated into steam.
[0093] It should be noted that, in some other embodiments, the steam pipe 122 may also be arranged on other side walls of the upper cover 12 , that is, the steam outlet 102 may also be arranged on other outer walls of the upper cover 12 .
[0094] See also Figures 4 to 11 As shown, in some embodiments, a pressure relief pipe 124 may be convexly provided on the top of the upper cover 12. The pressure relief pipe 124 may be arranged to extend upward from the top surface of the upper cover 12. A pressure relief port 103 may be formed in the pressure relief pipe 124. The pressure relief port 103 is connected to the steam chamber 140 in the upper cover 12. When the steam outlet 102 is blocked and the steam pressure in the steam chamber 140 is too high, the steam chamber 140 may be connected to the outside of the shell 1 through the pressure relief port 103, and then the steam in the steam chamber 140 is discharged to the outside of the shell 1, so as to keep the working safety of the steam generator.
[0095] It should be noted that, in other embodiments, the pressure relief pipe 124 may also be protruded on the side wall of the upper cover 12. The pressure relief pipe 124 may be arranged to protrude outwardly from the side wall of the upper cover 12 in a transverse direction.
[0096] In some embodiments, a blocking cover 4 may be sleeved on the pressure relief pipe 124. The blocking cover 4 may block the pressure relief port 103, so that during normal operation, the steam in the steam chamber 140 will not be discharged from the pressure relief port 103, and the steam in the steam chamber 140 will be discharged from the housing 1 from the steam outlet 102.
[0097] See also Figures 4 to 8 As shown, in some embodiments, a first temperature control unit 5, such as a first temperature controller, may be provided outside the housing 1. The first temperature control unit 5 may be provided on the outer wall of the heating base 11. The first temperature control unit 5 may be arranged opposite to the first heating chamber 110. The first temperature control unit 5 may be used to detect the temperature in the first heating chamber 110.
[0098] In some embodiments, the first temperature control unit 5 can be disposed on the bottom surface of the heating base 11. The first temperature control unit 5 can be disposed directly below the first heating chamber 110. In other embodiments, the first temperature control unit 5 can also be disposed on the side wall of the heating base 11, and the first temperature control unit 5 can be disposed outside the first heating chamber 110.
[0099] See also Figures 4 to 8 As shown, in some embodiments, the first temperature control unit 5 can be connected to the heating element 2 by signal. The first temperature control unit 5 can control the heating element 2 to work according to the temperature in the first heating chamber 110. The first temperature control unit 5 can control the heating element 2 to start heating or stop heating. When the first temperature control unit 5 controls the heating element 2 to start heating, the temperature in the first heating chamber 110, the second heating chamber 120, and the third heating chamber 130 inside the housing 1 will continue to rise. When the first temperature control unit 5 controls the heating element 2 to stop heating, the temperature in the first heating chamber 110, the second heating chamber 120, and the third heating chamber 130 inside the housing 1 will continue to decrease.
[0100] See also Figures 4 to 8 As shown, in some embodiments, the first temperature control unit 5 can be connected to the water inlet valve signal. The first temperature control unit 5 can control the water inlet valve to work according to the temperature in the first heating chamber 110. The first temperature control unit 5 can control the water inlet valve to open or close the water inlet 101.
[0101] In some embodiments, when the temperature in the first heating chamber 110 is higher than the first preset temperature (such as 130°C), the first temperature control unit 5 can control the heating element 2 to stop heating, and the first temperature control unit 5 can control the water inlet valve to open the water inlet 101 to allow external water to enter the first heating chamber 110. The temperature in the first heating chamber 110 can begin to decrease, thereby preventing the steam temperature inside the shell 1 from being too high and the steam pressure from being too high.
[0102] In some embodiments, when the temperature in the first heating chamber 110 is lower than the second preset temperature (e.g., 110°C), the first temperature control unit 5 can control the water inlet valve to close the water inlet 101, so that the external water stops entering the first heating chamber 110, and the single water inlet volume of the water inlet valve can be controlled. The first temperature control unit 5 can also control the heating element 2 to restart heating. When the temperature in the first heating chamber 110 is reheated to the first preset temperature, the first temperature control unit 5 can control the heating element 2 to stop heating, and then repeat the above process to generate steam in sequence.
[0103] See also Figures 7 and 8 As shown, in some embodiments, a first mounting groove 115 may be recessed on the bottom surface of the housing 1, and the first mounting groove 115 may be recessed on the bottom surface of the heating base 11. The first temperature control unit 5 may be installed in the first mounting groove 115. The first mounting groove 115 may reduce the distance between the first temperature control unit 5 and the first heating chamber 110, thereby improving the temperature detection accuracy of the first temperature control unit 5.
[0104] It should be noted that, in other embodiments, the first mounting groove 115 may also be arranged on other outer side walls of the first heating chamber 110 corresponding to the heating base 11 .
[0105] See also Figures 4 to 8 As shown, in some embodiments, a second temperature control unit 6, such as a second temperature controller, may be provided outside the housing 1. The second temperature control unit 6 may be provided on the outer wall of the heating base 11. The second temperature control unit 6 may be arranged opposite to the second heating chamber 120. The second temperature control unit 6 may be used to detect the temperature in the second heating chamber 120.
[0106] In some embodiments, the second temperature control unit 6 can be disposed on the bottom surface of the heating base 11. The second temperature control unit 6 can be disposed directly below the second heating chamber 120. In other embodiments, the second temperature control unit 6 can also be disposed on the side wall of the heating base 11, and the second temperature control unit 6 can be disposed outside the second heating chamber 120.
[0107] In some embodiments, the second temperature control unit 6 can be connected to the heating element 2 by signal. The second temperature control unit 6 can control the heating element 2 to work according to the temperature in the second heating chamber 120. The second temperature control unit 6 can control the heating element 2 to start heating or stop heating.
[0108] In some embodiments, when the heating element 2 starts heating, the temperature in the first heating chamber 110, the second heating chamber 120, and the third heating chamber 130 inside the housing 1 will continue to rise. When the temperature in the second heating chamber 120 is higher than the third temperature (e.g., 150° C.), the second temperature control unit 6 can control the heating element 2 to stop heating to prevent the temperature in the second heating chamber 120 and the steam chamber 140 from being too high.
[0109] See also Figures 7 and 8 As shown, in some embodiments, the bottom surface of the housing 1 may be concavely provided with a second mounting groove 116, and the second mounting groove 116 may be concavely provided on the bottom surface of the heating base 11. The second temperature control unit 6 may be installed in the second mounting groove 116. The second mounting groove 116 may reduce the distance between the second temperature control unit 6 and the second heating chamber 120, thereby improving the temperature detection accuracy of the second temperature control unit 6.
[0110] It should be noted that, in other embodiments, the second mounting groove 116 may also be arranged on other outer side walls of the second heating chamber 120 corresponding to the heating base 11 .
[0111] See also Figures 4 to 8As shown, in some embodiments, a timing unit 7, such as a timer, may be provided outside the housing 1. The timing unit 7 is connected to the first temperature control unit 5 by signal. When the first temperature control unit 5 detects that the temperature of the first heating chamber 110 reaches the first preset temperature, the first temperature control unit 5 can open the water inlet valve to allow external water to enter the first heating chamber 110 through the water inlet 101. When the first temperature control unit 5 controls the water inlet valve to open, the first temperature control unit 5 can control the opening time of the water inlet valve through the timing unit 7, for example, control the water inlet valve to close after the water inlet valve is opened for a preset time period, thereby accurately controlling the water inflow of the water inlet 101.
[0112] It should be noted that, since the water inlet temperatures of the first temperature control unit 5 and the water inlet 101 are different, the temperature changes in the first heating chamber 110 are also different. Therefore, the opening time of the water inlet valve is controlled only by the detected temperature of the first temperature control unit 5, which has great uncertainty, and it is easy to cause excessive overflow of water in the second heating chamber 120, or too little water in the second heating chamber 120. However, through the timing control of the timing unit 7, the operation of the water inlet valve can be more accurately controlled, and then the single water inlet amount of the steam generator can be accurately controlled, so that the water amount in the second heating chamber 120 can be maintained within a certain height range after each water inlet, effectively improving the steam formation efficiency, and preventing excessive water from overflowing the second heating chamber 120 into the steam chamber 140, thereby solving the water spraying problem when steam is sprayed out from the steam outlet 102.
[0113] See also Figures 7 and 8 As shown, in some embodiments, the timing unit 7 can be arranged on the bottom surface of the heating base 11. It should be noted that, in other embodiments, the timing unit 7 can also be arranged on other outer side walls of the heating base 11, or the timing unit 7 can also be arranged on the outer wall of the upper cover 12.

The steam generator may provide steam to the inside of the clothing treatment chamber through the steam nozzle to perform steam care on the clothing, which can be used for wrinkle removal, deodorization, and health-related functions such as sterilization and mite removal.
[0118] It should be noted that, in other embodiments, the steam nozzle may also be arranged on other outer walls of the cylinder. The steam nozzle may also be directly extended into and arranged inside the clothing processing chamber. In other embodiments, the steam nozzle may also be arranged in a drying air duct connected to the clothing processing chamber.

The first temperature control unit 5 can control the heating element 2 to start heating or stop heating. The temperature in the first heating chamber 110 can be detected by the first temperature control unit 5, and then when the preset temperature is reached, the first temperature control unit 5 can open the water inlet valve, and the timing unit 7 is used to time and control the opening time of the water inlet valve, thereby accurately controlling the water intake of the steam generator and improving the clothing care effect.
