In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] See also Figures 1 to 5 The present embodiment provides a steam brush, which includes a housing 1, a nozzle 2 and a water tank 3. A water inlet 31 is provided at the top of the water tank 3. A plunger 4 is detachably installed in the water inlet 31. The plunger 4 is at least partially located outside the housing 1. A user can fill water into the water tank 3 by disassembling the plunger 4. Specifically, in the present embodiment, the water tank 3 is installed inside the housing 1, and the water inlet 31 partially extends out of the housing 1. A user can open or close the water inlet 31 by disassembling the plunger 4, so as to replenish water into the water tank 3.

[0040] It can be understood that in this embodiment, the plunger 4 is screwed into the water inlet 31, and the user can open or close the water inlet 31 by turning the knob of the plunger 4. Of course, in other optional embodiments, the plunger 4 can also be detachably installed in the water inlet 31 by other methods such as plugging and unplugging, and this is not specifically limited in this embodiment.

[0041] In addition to the shell 1, the nozzle 2 and the water tank 3, the steam brush also includes a reaction box 5 and a steam channel 7, wherein the reaction box 5 is installed inside the shell 1, a steam chamber 51 is formed in the reaction box 5, a heater 52 is installed in the steam chamber 51, a water inlet hole 32 is provided at the bottom of the water tank 3, a plug 33 is installed in the water inlet hole 32, the plug 33 has a first working position for blocking the water inlet hole 32, and a second working position for conducting the water inlet hole 32, when the plug 33 is located at the second working position, the water tank 3 is connected with the steam chamber 51 through the water inlet hole 32, at this time, the water in the water tank 3 can be injected into the steam chamber 51 through the water inlet hole 32, the heater 52 can heat the water injected into the steam chamber 51 to generate steam, and the generated steam can be discharged through the steam channel 7, specifically, one end of the steam channel 7 is connected with the steam chamber 51, and the other end of the steam channel 7 is connected with the nozzle 2, the steam generated by heating can flow to the nozzle 2 through the steam channel 7 and be sprayed out through the nozzle 2.

[0042] It is understandable that the specific structure of the heater 52 is prior art, and therefore, it will not be described in detail in this embodiment.

[0043] In addition, the steam brush also includes an air inlet pipe 6, one end of which extends into the steam chamber 51 and is located above the heater 52. The end of the air inlet pipe 6 extending into the steam chamber 51 is connected to the steam chamber 51, and the other end of the air inlet pipe 6 is connected to the top space of the water tank 3. When the water in the steam chamber 51 submerges the port at one end of the air inlet pipe 6 extending into the steam chamber 51, the water in the water tank 3 cannot be injected into the steam chamber 51 through the water inlet hole 32. Correspondingly, when the water level in the steam chamber 51 is lower than the port at one end of the air inlet pipe 6 extending into the steam chamber 51, the water in the water tank 3 can be injected into the steam chamber 51 through the water inlet hole 32.

[0044] Specifically, in this embodiment, after the user has finished filling water into the water tank 3, the plug 33 is kept in the second working position, that is, the water inlet hole 32 is in a normally open state, and under the blocking of the plunger 4, the water tank 3 is isolated from the outside. Afterwards, whether the water tank 3 fills water into the steam chamber 51 depends on the water level in the steam chamber 51. Initially, the water level in the steam chamber 51 is lower than the port at one end of the air inlet pipe 6 extending into the steam chamber 51. At this time, the water tank 3 keeps filling water into the steam chamber 51, and when the water level in the steam chamber 51 is After the water covers the port at one end of the air inlet pipe 6 extending into the steam chamber 51, the water in the water tank 3 cannot be injected into the steam chamber 51 through the water inlet hole 32. As the steam generated by heating is gradually discharged through the steam channel 7, the water level in the water tank 3 will drop. When the water level in the steam chamber 51 drops to below the port at one end of the air inlet pipe 6 extending into the steam chamber 51, the water tank 3 resumes injecting water into the steam chamber 51 until the water in the steam chamber 51 covers the port at one end of the air inlet pipe 6 extending into the steam chamber 51 again.

[0045] That is, in this embodiment, the user directly fills water into the water tank 3, and then the water tank 3 supplies water to the steam chamber 51. Moreover, this embodiment controls the water in the steam chamber 51 to maintain a low water level through the air inlet pipe 6, thereby controlling the steam chamber 51 to maintain a small amount of water. On the one hand, the heater 52 can quickly heat the water in the steam chamber 51 and generate steam, so as to avoid the user having to wait for a long time when using the steam brush, thereby improving the user experience. On the other hand, when the user shakes the steam brush during use, the boiling water in the reaction box 5 is not easy to spray out from the nozzle, thereby avoiding threats to user safety.

[0046] Based on the above, in the present embodiment, the plug 33 passes through the water inlet hole 32, and there is a clearance fit between the plug 33 and the hole wall of the water inlet hole 32. The plug 33 is respectively provided with a first abutment portion 331 and a second abutment portion 332 at both ends of the axial direction of the water inlet hole 32. The steam brush also includes a push rod 91 and a spring 92. The push rod 91 can push the plug 33 to move along the axial direction of the water inlet hole 32 toward the side close to the steam chamber 51, so that the plug 33 moves from the first working position to the second working position. When the plug 33 is in the first working position, the first abutment portion 331 blocks the water inlet hole 32. On the side of the water hole 32 close to the steam chamber 51, the spring 92 is sleeved on the outer periphery of the plug 33 and abuts between the second abutting portion 332 and the bottom wall of the water tank 3. That is, in this embodiment, the plug 33 is pushed by the push rod 91 to open the water inlet hole 32, thereby connecting the water tank 3 and the steam chamber 51. When the user fills water into the water tank 3, the push rod 91 releases the push on the plug 33, and the plug 33 is reset from the second working position to the first working position under the action of the spring 92, thereby blocking the water inlet hole 32, thereby preventing the water injected into the water tank 3 from flowing into the steam chamber 51 when water is filled into the water tank 3.

[0047] Furthermore, the push rod 91 is fixedly connected to the plunger 4 and is coaxially arranged with the plunger 4, and the water injection port 31 is coaxially arranged with the water inlet hole 32. When the user takes the plunger 4 out of the water injection port 31, the push rod 91 releases the push on the plug 33, thereby resetting the plug 33 from the second working position to the first working position, thereby blocking the water inlet hole 32. When the user re-inserts the plunger 4 into the water injection port 31, the push rod 91 automatically pushes the plug 33 from the first working position to the second working position, thereby opening the water inlet hole 32, and the plug 33 is then maintained in the second working position. That is, in this embodiment, the movement of the plug 33 is automatically completed as the user disassembles and assembles the plunger 4, and the user does not need to perform additional operations before removing the plunger 4 or after re-installing the plunger 4, thereby simplifying the user's operation and further improving the user experience.

[0048] In addition, in the present embodiment, the diameter of the first abutment portion 331 gradually increases from the side close to the second abutment portion 332 to the side away from the second abutment portion 332, the diameter of the side of the first abutment portion 331 close to the second abutment portion 332 is smaller than the diameter of the water inlet hole 32, and the diameter of the side of the first abutment portion 331 away from the second abutment portion 332 is larger than the diameter of the water inlet hole 32, thereby increasing the sealing performance of the plug 33 located at the first working position to the water tank 3.

[0049] Further, the bottom wall of the water tank 3 is provided with a first boss 34 and a second boss 35, the first boss 34 and the second boss 35 are respectively located inside and outside the water tank 3, the first boss 34 is provided with a first cavity 341, the second abutting portion 332 is located in the first cavity 341, and the second abutting portion 332 and the cavity wall of the first cavity 341 are in a clearance fit, the first boss 34 can provide a guide for the movement of the second abutting portion 332, thereby ensuring that the plug 33 can stably move along its axial direction. In addition, the second boss 35 is provided with a second cavity 351, the first abutting portion 331 is located in the second cavity 351, and the first abutting portion 331 and the cavity wall of the second cavity 351 are in a clearance fit, the second boss 35 can provide a guide for the movement of the first abutting portion 331, thereby ensuring that the plug 33 can more stably move along its axial direction, and the second boss 35 will not affect the water tank 3 from injecting water into the steam chamber 51.

[0050] It should be noted that a through hole 342 is provided on the side of the first boss 34 , and the through hole 342 connects the external space of the first boss 34 and the first cavity 341 , thereby ensuring that the water in the water tank 3 can smoothly flow into the steam chamber 51 through the water inlet hole 32 .

[0051] Furthermore, a guide block 36 is fixedly connected to the inside of the water tank 3. Specifically, in the present embodiment, the guide block 36 is fixedly connected to the first boss 34. The guide block 36 is provided with a guide hole 361. The guide hole 361 is coaxially arranged with the water inlet hole 32. The push rod 91 can pass through the guide hole 361 and push against the plug 33. The guide block 36 can provide a guiding effect on the movement of the push rod 91, thereby ensuring that the push rod 91 can push against the plug 33 and stably move along its axial direction.

[0052] In addition, in this embodiment, the air intake pipe 6 includes a first pipe fitting, a second pipe fitting 62 and a third pipe fitting 63, wherein the first pipe fitting is integrally formed at the bottom of the water tank 3, the first pipe fitting includes a first pipe portion 611 and a second pipe portion 612 that are connected, the first pipe portion 611 is located outside the water tank 3 and extends into the steam chamber 51, the second pipe portion 612 is located inside the water tank 3, the second pipe fitting 62 is integrally formed at the top of the water tank 3, the third pipe fitting 63 is located in the water tank 3, one end of the third pipe fitting 63 is sleeved on the outer periphery of the second pipe portion 612, and the other end of the third pipe fitting 63 is sleeved on the outer periphery of the second pipe fitting 62, and one end of the second pipe fitting 62 away from the third pipe fitting 63 is connected to the internal space of the water tank 3, thereby connecting the steam chamber 51 with the top space of the water tank 3.

[0053] Based on the above, since the end of the air inlet pipe 6 extending into the steam chamber 51 is integrally formed on the water tank 3, the present embodiment can ensure that when the water in the steam chamber 51 submerges the port at the end of the air inlet pipe 6 extending into the steam chamber 51, no gas exchange occurs between the water tank 3 and the steam chamber 51, thereby effectively ensuring that the water in the water tank 3 cannot be injected into the steam chamber 51 through the water inlet hole 32. In addition, the lower end of the third pipe 63 is sleeved on the outer periphery of the second pipe portion 612 located below, and the upper end of the third pipe 63 is sleeved on the outer periphery of the second pipe 62 located above, thereby ensuring that the third pipe 63 is firmly installed in the water tank 3.

[0054] Furthermore, the outer cover of the water tank 3 is provided with a surrounding plate 8, and a steam channel 7 is formed between the surrounding plate 8 and the water tank 3, so that the steam can be transported to the nozzle.
