[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0036] like Figures 1 to 5 As shown, this embodiment discloses a steam cleaning head, which includes a body 1 and a cleaning accessory adapted to the body 1. Preferably, the connecting handle 1.1 is connected to the connecting head 1.2 at an angle of 40-50°, preferably 45°. The cleaning accessory is a breathable cleaning sleeve 2, so the steam cleaning head is used for ironing clothes or cleaning walls and floors.

[0037] The body 1 is an injection molded part, and thus has an integrally connected connection handle 1.1 and a connection head 1.2 located at the end of the connection handle 1.1. The connection head 1.2 is a thin-walled structural part with a longitudinal skirt 1.2h, and the bottom of the entire longitudinal skirt 1.2h is located on the same plane, so that it can fit the surface of the object to be cleaned. Two snap connection parts 1.2c are symmetrically arranged on the rear side of the connection head 1.2.

[0038] The connecting handle 1.1 is used to connect the steam pipe, and therefore has a connecting cavity 1.1a and a steam channel 1.1c extending from the connecting cavity 1.1a and penetrating to the center of the bottom of the connecting head 1.2. The connecting handle 1.1 can be used as a handle directly by hand, or it can be connected to an extension rod to expand the cleaning range. The end of the steam pipe is inserted into the connecting cavity 1.1a to achieve connection. Preferably, an air intake connector 1.1b is provided at the connection between the connecting cavity 1.1a and the beginning of the steam channel 1.1c. The air intake connector 1.1b is connected to the end of the steam pipe to achieve steam delivery.

[0039] Preferably, the steam channel 1.1c extends to the bottom center of the connector 1.2 to form an extension 1.2a, and a steam outlet 1.2b is provided on the side of the extension 1.2a, and 2-4 steam outlets 1.2b are provided. The advantage of this steam outlet method is that the steam will not immediately act on the breathable cleaning cover 2 below, but diffuse to the periphery, and act more evenly on the entire breathable cleaning cover 2 below, avoiding the situation where the local temperature is high and the surrounding temperature is low.

[0040] Preferably, the bottom of the connector 1.2 is provided with a steam chamber 1.2d extending in the longitudinal direction and flush with the bottom of the longitudinal skirt 1.2h, and the extension 1.2a is located in the steam chamber 1.2d. The steam chamber 1.2d not only supports the breathable cleaning sleeve 2, but also reduces the area of ​​the entire heating area, so that the temperature of the breathable cleaning sleeve 2 is higher. Obviously, the width dimension of the steam chamber 1.2d in the left-right direction is greater than the width dimension in the front-back direction, so that the breathable cleaning sleeve 2 can be heated and heated as a whole in the width direction.

[0041] Preferably, the connector 1.2 is provided with front and rear ribs 1.2f, 1.2g and side ribs 1.2e for connecting the steam chamber 1.2d. The front rib 1.2f is located at the front side of the steam chamber 1.2d and connected to the front wall of the longitudinal skirt 1.2h. The rear rib 1.2g is located at the rear side of the steam chamber 1.2d and connected to the rear wall of the longitudinal skirt 1.2h. The side rib 1.2e is located at the left and right sides of the steam chamber 1.2d and connected to the left and right walls of the longitudinal skirt 1.2h. The bottom of the side rib 1.2e is flush with the bottom of the longitudinal skirt 1.2h and the steam chamber 1.2d.

[0042] The breathable cleaning sleeve 2 comprises a sleeve body 2.1 and an elastic closing strip 2.2 located at the mouth of the sleeve body 2.1, and is sleeved on the connector 1.2 through the elastic closing strip 2.2. The breathable cleaning sleeve 2 is installed on the connector 1.2 in a sleeve-type manner, which is more convenient to install than the press-fitting manner in the prior art, and can make the structure of the body 1 simpler. Preferably, the sleeve body 2.1 is a cotton braided sleeve, and the elastic closing strip 2.2 is a rubber band. Example

[0043] like Figure 6-10 As shown, the difference between this embodiment and the first embodiment is that the cleaning accessory is a flat brush 3, so the steam cleaning head is used to clean large flat surfaces such as walls, floors or glass surfaces. The flat brush 3 is an injection molded part, which has a brush plate 3.1, a scraper 3.2 located at the bottom or front of the brush plate 3.1, front and rear buckles 3.1c and 3.1d located at the top of the brush plate 3.1, and a vent 3.1b located on the brush plate 3.1, and the steam is discharged from the vent 3.1b to act on the surface of the object. The scraper 3.2 is located in front of the vent 3.1b and is set at an obtuse angle to the brush plate 3.1. The flat brush 3 is clamped on the connector 1.2 by the front buckle 3.1c and the rear buckle 3.1d. The front buckle 3.1c is used to form a snap connection with the front top surface of the connecting head 1.2, and the rear buckle 3.1d is used to form a one-to-one snap connection with the buckle connection part 1.2c on the rear side of the connecting head 1.2, thereby realizing the constraint of the flat brush 3 and the connecting head 1.2 in the front-to-back and up-down directions.

[0044] When in use, the scraper 3.2 is placed against the surface of an object, steam is ejected from the rear thereof onto the surface of the object, and then the scraper 3.2 is operated to scrape backwards to remove dirt on the surface.

[0045] Preferably, the brush plate 3.1 further comprises a first limiting protrusion 3.1e for limiting the downward movement of the steam chamber 1.2d and a second limiting protrusion 3.1a for limiting the left and right movement of the longitudinal skirt 1.2h. Two first limiting protrusions 3.1e are symmetrically arranged, forming limiting constraints on the left and right sides of the longitudinal skirt 1.2h respectively to prevent it from moving left and right. The second limiting protrusion 3.1a forms a limiting constraint with the top of the steam chamber 1.2d to prevent it from moving up and down.

[0046] Preferably, the scraper 3.2 is a silicone or rubber scraper, so as to form good contact with the surface of the object and avoid cleaning dead corners. Example

[0047] The present invention further provides a steam cleaning device, comprising a device body and a steam cleaning head connected to the device body through a steam pipe, wherein the steam cleaning head is the steam cleaning head in the first embodiment or the second embodiment.

[0048] Preferably, the steam cleaning device further comprises an extension rod, through which the steam cleaning head is connected to the steam pipe, thereby expanding the cleaning range. The device body and the connection method with the steam cleaning head are both prior art, so they are not described in detail.

[0049] It can be seen from Example 1 and Example 2 that when changing the application scenario, only the cleaning accessories need to be replaced, and the main body 1 does not need to be replaced. Therefore, compared with the method of replacing the entire steam cleaning head in the prior art, the number of steam cleaning heads is significantly reduced, which is not only convenient for replacement, but also more convenient for daily storage and organization.
