[0038] Figure 1 Schematic diagram of the overall structure of the host provided for the embodiments of the present invention; Figure 2 Cross-sectional view of the host provided for the embodiments of the present invention.

[0039] As Figure 1 Combined with Figure 2As shown in the figure, the present invention provides a main unit, including a housing 1, a water inlet pipe 2, a heating element 4 and a vaporization cover 401; the heating element 4 is arranged inside the housing 1, the vaporization cover 401 is covered at the end of the heating element 4 along the length direction of the heating element 4, and forms a first vaporization chamber 3 with the heating element 4; the water inlet pipe 2 is arranged inside the housing 1, and one end of the water inlet pipe 2 is communicated with the first vaporization chamber 3; an air outlet 101 is formed at one end of the housing 1, one end of the air outlet 101 is communicated with the exhaust port 301 of the first vaporization chamber 3, the cross-sectional area of the end of the air outlet 101 facing the exhaust port 301 is larger than the cross-sectional area of the exhaust port 301, and the side wall of one side of the air outlet 101 and the side wall of one side of the exhaust port 301 are arranged in a stepped manner, and the height difference between the side wall of one side of the air outlet 101 and the side wall of one side of the exhaust port 301 is not more than 4 mm.

[0040] Compared with the prior art, the main unit provided by the present invention has the following advantages:

[0041] For the main unit provided by the present invention, the heating element 4 and the vaporization cover 401 arranged inside the housing 1 can enclose and form a closed first vaporization chamber 3, and then the required amount of water is injected into the first vaporization chamber 3 through the water inlet pipe 2. After the heating element 4 vaporizes the water, it is discharged from the exhaust port 301. Since the cross-sectional area of the end of the air outlet 101 facing the exhaust port 301 is larger than the cross-sectional area of the exhaust port 301, on the one hand, it can make the vaporized steam flow more smoothly to the brush head 8, and on the other hand, it can make the scale in the first vaporization chamber 3 pass through the exhaust port 301 and directly flow out from the air outlet 101.

[0042] Since the side wall of one side of the air outlet 101 and the side wall of one side of the exhaust port 301 in the present application are arranged in a stepped manner, further, the scale to be cleaned can flow out smoothly, avoiding residue and backflow.

[0043] It should be supplemented and explained here that the heating element 4 in the present application can be a heating pipe, a heating wire or other structures that can generate heat after being electrified, so as to realize the vaporization of water. Preferably, the heating element 4 in the present application has a plurality of U-shaped grooves, and a plurality of first vaporization chambers 3 can be formed by the vaporization cover 401 arranged along the length direction of the heating element 4 at the open end, and the plurality of first vaporization chambers 3 are mutually communicated, so that the formed steam can be discharged from the air outlet 101.

[0044] A cleaning button can be provided on the main unit in the present application. The cleaning button is electrically connected to the controller. When the cleaning button of the main unit is pressed, the controller controls the water pump to inject a large flow of water into the first vaporization chamber 3, and through the water and steam mixture with a strong impact force generated instantaneously, the impurities and scale in the first vaporization chamber 3 are discharged from the exhaust port 301 of the heating element 4 through the air outlet 101, so as to achieve the effect of cleaning the inside of the first vaporization chamber 3.

[0045] Among them, such asFigure 1 Combined with Figure 2 As shown, the main body provided by the present invention further includes a seal, a water inlet joint 5 and a water pump; the seal is disposed at the air outlet 101, and a through hole is provided along the axial direction of the seal, and the through hole is in communication with the air outlet 101; one end of the water inlet joint 5 is in communication with one end of the water inlet pipe 2, and the other end of the water inlet joint 5 is in communication with the first vaporization chamber 3; the water pump is in communication with the end of the water inlet pipe 2 away from the water inlet joint 5 for pumping water into the first vaporization chamber 3.

[0046] In this application, by providing a seal, the steam in the first vaporization chamber 3 can be more concentratedly output to the brush head 8. Preferably, the seal in this application is a silica gel sleeve 102. When the air outlet 101 of the main body is provided with the silica gel sleeve 102, the air outlet 101 is formed by the silica gel sleeve 102, and the air outlet end of the main body is a through hole channel 1021. The outer wall of the silica gel sleeve 102 fits the inner wall surface of the through hole channel 1021.

[0047] In this application, by providing the water inlet joint 5, the distance between the water inlet pipe 2 and the first vaporization chamber 3 can be increased to a certain extent, thereby reducing the problem that the water inlet pipe 2 is damaged due to the too close distance between the water inlet pipe 2 and the first vaporization chamber 3.

[0048] Providing a water pump at the end of the water inlet pipe 2 away from the water inlet joint 5 can increase the water inlet pressure. When it is necessary to clean the scale in the first vaporization chamber 3, the scale in the first vaporization chamber 3 can be flushed out by high-pressure water flow and steam.

[0049] It should be supplemented and explained here that preferably, the water inlet joint 5 in this application is provided in an L shape, with one end in communication with the water inlet pipe 2 and the other end in communication with the first vaporization chamber 3. The L-shaped water inlet joint 5 can make the internal structure of the main body more regular and better arranged.

[0050] Specifically, as Figure 1 Combined with Figure 2 As shown, one end of the housing 1 facing the brush head 8 of the steam brush is provided with a first contact 6 and a second contact 7; the first contact 6 and the second contact 7 are used to provide power or electrical signals for the brush head 8.

[0051] The brush head 8 in this application is powered by the main body, and a first contact 6 and a second contact 7 are provided on one side of the housing 1 facing the brush head 8. When the third contact 801 on the brush head 8 contacts the first contact 6 on the housing 1 and the fourth contact 802 contacts the second contact 7, the brush head 8 can be quickly powered on.

[0052] It should be supplemented and explained here that in this application, the first contact 6 and the second contact 7 can also provide electrical signals to the brush head 8 to realize the start and stop of the heating element 12 in the brush head 8.

[0053] Figure 3 A cross-sectional view of the main body provided in the embodiment of the present invention with a silica gel sleeve; Figure 4 A schematic diagram of the overall structure of the steam brush provided in the embodiment of the present invention; Figure 5 An exploded view of the brush head of the steam brush provided in the embodiment of the present invention from a first perspective; Figure 6 A schematic diagram of the structure of the end cap of the steam brush provided in the embodiment of the present invention from a first perspective.

[0054] In addition, as Figures 1 - 6 shown, the present invention further provides a steam brush, including the above-mentioned main body and a plurality of brush heads 8; the plurality of brush heads 8 and the housing 1 are both detachably connected, and at the positions corresponding to the first contact 6 on the brush head 8, a third contact 801 is provided, and at the position corresponding to the second contact 7, a fourth contact 802 is provided.

[0055] When it is necessary to clean and discharge the scale in the first vaporization chamber 3, the brush head 8 is removed, and high-pressure water flow is injected into the first vaporization chamber 3 through a water pump. Part of the water in the first vaporization chamber 3 forms steam through the heating element 4, and the scale is directly flushed out of the air outlet 101 under the dual action of the water flow and the steam.

[0056] Since the brush head 8 and the main body in the present application are detachably connected, the scale can be directly discharged from the air outlet 101, thereby solving to a certain extent the problem that the diameter of the air outlet 901 of the brush head 8 is too small, resulting in the scale being unable to be discharged smoothly and blocking the air outlet 901 of the brush head 8.

[0057] It should be supplemented and explained here that preferably, the first contact 6 and the third contact 801, and the second contact 7 and the fourth contact 802 in the present application are all weakly electrically connected, and the voltages at the first contact 6, the second contact 7, the third contact 801, and the fourth contact 802 are all safe voltages, so as to avoid the problem of electric shock to personnel when the brush head 8 is removed.

[0058] Among them, as Figures 1 - 6 shown, the plurality of brush heads 8 all include a panel 9, a cover plate 10, a heating element 12, and an end cap 11; a plurality of air outlets 901 penetrating through the panel 9 are formed on the panel 9, and a first convex portion 902 and a second convex portion 903 are formed on one side of the panel 9; the first convex portion 902 is annular and encloses the air outlets 901 within the first convex portion 902; the second convex portion 903 is semi-surroundingly arranged, the heating element 12 is located within the second convex portion 903 and is in contact with the panel 9, and the power-on column 1201 of the heating element 12 protrudes from the second convex portion 903; the cover plate 10 is buckled on the edge of the first convex portion 902 and forms a second vaporization chamber 904 with the panel 9, and a through hole 1002 communicating with the second vaporization chamber 904 is formed on the cover plate 10; and one end of the through hole 1002 far from the second vaporization chamber 904 is communicated with the air outlet 101.

[0059] Through the second convex part 903 formed on the panel 9 in a semi-surrounding setting, the heating element 12 can be stably installed within the second convex part 903, and the panel 9 can be heated by the heating element 12. Moreover, since the heating element 12 in this application is in contact with the panel 9, heat can be transferred to the panel 9 more quickly.

[0060] It should be noted here that the heating element 12 in this application can be directly fixed on the panel 9 by means such as bonding or welding.

[0061] In this application, through the annular first convex part 902 formed on the panel 9, when the cover plate 10 is buckled with the panel 9, a second vaporization chamber 904 can be formed, so that the steam entering the second vaporization chamber 904 can be further vaporized. Due to the secondary vaporization, the steam ejected from the air outlet 901 has stronger penetration power, thereby improving the ironing effect to a certain extent.

[0062] When the steam brush starts operating for the first time, the heating element 12 and the heating body 4 are started simultaneously. The panel 9 can be heated by the heating element 12. When the steam passes from the air outlet 101 through the air passing hole 1002 to the second vaporization chamber 904 formed by the buckling of the cover plate 10 and the first convex part 902, since the panel 9 is heated by the heating element 12, on the one hand, the steam can be vaporized for the second time, and on the other hand, it can to a certain extent avoid the problem that the temperature of the panel 9 is too low, resulting in a decrease in the steam temperature and the formation of water droplets spraying out of the brush head 8, thereby avoiding to a certain extent the problem that water droplets spray out of the brush head 8 and wet the clothes.

[0063] It should be noted here that a plurality of mounting posts are formed on the panel 9 in this application, mounting holes corresponding to the mounting posts on the panel 9 are provided on the cover plate 10 and the end cover 11, and both the cover plate 10 and the end cover 11 are connected to the panel 9 through positioning members.

[0064] Preferably, screw holes are provided on the plurality of mounting posts in this application, and both the end cover 11 and the cover plate 10 are installed and connected to the panel 9 through screws.

[0065] Preferably, the panel 9 in this application is an anti-rust metal panel, which can improve the service life of the brush head 8 on the one hand, and on the other hand, the metal panel has better heat conduction effect, so that the heating speed is faster.

[0066] Specifically, as Figures 1 - 6 shown, the cover plate 10 is provided with a ventilation column 1001, a mating hole 1101 corresponding to the ventilation column 1001 is provided on the end cover 11, and the air passing hole 1002 penetrates through the ventilation column 1001 along the axial direction of the ventilation column 1001; one end of the ventilation column 1001 can pass through the mating hole 1101, and when the brush head 8 is connected to the main body, the ventilation column 1001 can be inserted into the air outlet 101.

[0067] Preferably, the diameter of the ventilation column 1001 in the present application matches the mating hole 1101. On the one hand, when one end of the ventilation column 1001 passes through the mating hole 1101 and is inserted into the air outlet 101, the steam directly enters the second vaporization chamber 904 through the air passing holes 1002, making the steam more concentrated. On the other hand, since the cover plate 10 is located between the panel 9 and the end cover 11, by providing the ventilation column 1001 on the cover plate 10, it can play a positioning role for the end cover 11 during the process of the end cover 11 and the panel 9 being buckled together, enabling the mounting holes formed on the end cover 11 to quickly align with the mounting posts formed on the panel 9 to complete the buckling installation.

[0068] It should be added here that there can be multiple ventilation columns 1001 in the present application. Correspondingly, the mating holes 1101 on the end cover 11 are provided in one-to-one correspondence with the ventilation columns 1001.

[0069] When the brush head 8 is connected and installed to the main body, the ventilation column 1001 can be inserted into the air outlet 101, so that the brush head 8 can be more quickly connected and installed to the main body.

[0070] It should be added here that the air outlet 101 formed by the ventilation column 1001 and the silica gel sleeve 102 in the present application is interference sealed. By providing the silica gel sleeve 102, a part of the ventilation column 1001 can be inserted into the air outlet 101 formed by the silica gel sleeve 102, which not only increases the friction force, improves the connection strength between the brush head 8 and the main body, but also can ensure the airtightness to a certain extent, enabling the steam to pass through the air passing channel 1021, enter the air outlet 101, pass through the air passing holes 1002, and reach the second vaporization chamber 904.

[0071] Among them, as Figures 1 - 6 shown, the steam brush provided by the present invention further includes a controller and a thermistor 13. The controller is electrically connected to the heating element 12 and the thermistor 13 respectively, so that the controller can control the start and stop of the heating element 12 by collecting the temperature of the thermistor 13.

[0072] Preferably, the thermistor 13 in the present application is an NTC (Negative Temperature Coefficient) thermistor, the heating element 12 is a PTC (Positive Temperature Coefficient) heating element, and the controller is a PCB (Printed Circuit Board), that is, a printed circuit board. The PCB controls the on-off of the heating element 12 by collecting the temperature of the NTC thermistor.

[0073] When the temperature of the NTC thermistor reaches the set value, the PCB cuts off the heating of the PTC heating element. When the temperature is lower than the set value, the PCB starts the heating of the PTC heating element, so that the temperature of the metal panel can be accurately controlled. Moreover, multiple gears can be set through the PCB controller, and different temperature gears can be selected according to different fabrics.

[0074] It should be supplemented here that the heating element 12 in this application can also adopt a combination of an aluminum component and a PTC heating body, that is, the aluminum component is used as the housing 1 and sleeved outside the PTC heating body, and is fixedly connected to the panel 9.

[0075] Specifically, as Figures 1 - 6 shown, the end cover 11 is provided with a first conductive column 1102 and a second conductive column 1103; one end of the first conductive column 1102 protrudes from the end cover 11 to form a third contact 801, and the other end is connected to the energizing column 1201; one end of the second conductive column 1103 protrudes from the end cover 11 to form a fourth contact 802, and the other end is connected to the thermistor 13.

[0076] By providing the first conductive column 1102 and the second conductive column 1103 on the end cover 11, since one end of the first conductive column 1102 is connected to the energizing column 1201 of the heating element 12 and one end of the second conductive column 1103 is connected to the thermistor 13, when the brush head 8 is connected and installed to the host, the first contact 6 contacts the third contact 801, so that the host is connected to the heating element 12, and the second contact 7 contacts the fourth contact 802, so that the host is connected to the thermistor 13, thereby being able to provide power for the heating element 12 and the thermistor 13 and collect the temperature parameter of the thermistor 13.

[0077] It should be supplemented here that both the thermistor 13 and the heating element 12 in this application have two energizing columns 1201. Therefore, the number of the first conductive column 1102 and the second conductive column 1103 in this application is two.

[0078] Furthermore, as Figures 1 - 6 shown, a positioning convex portion 1104 is formed on the end cover 11. The positioning convex portion 1104 protrudes towards the direction close to the panel 9, and the positioning convex portion 1104 is aligned with the second convex portion 903, and is used to press the heating element 12 into the second convex portion 903.

[0079] When the end cover 11 is buckled with the panel 9, the positioning convex portion 1104 formed on the end cover 11 can press the heating element 12, so that the positioning and installation of the heating element 12 can be realized only by buckling the end cover 11 and the panel 9, with a simple structure and convenient installation.

[0080] Even further, as Figures 1 - 6As shown, a plurality of brush heads 8 include a first brush head and a second brush head. The size of the first brush head is larger than that of the second brush head, and the number of air outlets 901 of the first brush head is greater than that of the second brush head.

[0081] In this application, the size of the first brush head is larger than that of the second brush head, so that the number of air outlets 901 of the first brush head is more than that of the second brush head. Thus, the first brush head is more suitable for ironing large-sized clothes, and the second brush head is suitable for ironing small-sized clothes. Furthermore, the overall steam brush can be adapted to clothes of different sizes and thicknesses.

[0082] It should be noted here that the brush heads 8 of the steam brush in this application are not limited to two, and can include a plurality of brush heads 8 with different sizes and functions to be adapted according to different needs and the items to be ironed.

[0083] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
