[0002] In daily life, clothes usually develop more or less wrinkles after washing or wearing. Over time, they may even deform. People need to use a garment steamer or other ironing equipment to iron out the wrinkles and deformations of clothes. There are many types of ironing equipment available, and the most popular ones are undoubtedly handheld steam garment steamers. Handheld steam garment steamers generally include a water tank, a generator, and a nozzle. The water tank is the water source for the generator, which evaporates the water into steam and sprays it from the nozzle to iron the clothes hung on the hanger. In order to facilitate carrying, the handles of existing handheld garment steamers usually have a folding function, which can reduce the total volume by folding the handles.

Under the elastic action of the first compression spring 208, a downward tightening force can be applied to the first pressing block 205, thereby achieving close contact between the first pressing block 205 and the second elastic rubber sleeve 206;

[0035] A first elastic non-slip rubber 212 is bonded and fixed to the left side of the top of the garment steamer head 100. The top of the first elastic non-slip rubber 212 is in close contact with a second elastic pressing component. The second elastic pressing component includes a second pressing block 211 that is in movably contact with the top of the first elastic non-slip rubber 212. The bottom of the second pressing block 211 is bonded and fixed with a second elastic non-slip rubber. The bottom of the second elastic non-slip rubber is in close contact with the top of the first elastic non-slip rubber 212. The top of the second pressing block 211 is fixedly connected to a second movable rod 213. A second rectangular groove 210 is formed on the right side of the top inner wall of the protective cover 201. A second pressing block 211 is slidably sleeved in the second rectangular groove 210. A second compression spring 214 in a compressed state is fixedly connected between the top of the second pressing block 211 and the top inner wall of the second rectangular groove 210. The second compression spring 214 is movably sleeved on the second moving rod 213. Under the elastic force of the second compression spring 214, a downward tightening force is applied to the second pressing block 211, thereby achieving fixation between the protective cover 201 and the garment steamer head 100.

[0036] The top of the first moving rod 207 and the top of the second moving rod 213 are extended to the top of the protective cover 201 and are fixedly connected to the connecting rod 209. The top of the connecting rod 209 is fixedly connected to the U-shaped handle. The first moving rod 207 and the second moving rod 213 can be driven synchronously by the cooperation of the U-shaped handle and the connecting rod 209. A first sliding hole is opened on the top inner wall of the rotating hole 203, and a second sliding hole is opened on the top inner wall of the second rectangular groove 210. The inner wall of the first sliding hole and the inner wall of the second sliding hole are respectively connected to the first moving rod 207 and the second moving rod 213. The outer side of 7 is in sliding contact with the outer side of the second moving rod 213, and the first sliding hole and the second sliding hole are used for the first moving rod 207 and the second moving rod 213 to pass through respectively; the utility model is configured through a series of structures, so that the handle 101 can be folded and fixed after use, and the protective cover 201 can be rotated and fixed, and the nozzle on the left side of the garment steamer head 100 is shielded and protected by the protective cover 201, which can effectively reduce the dust and impurities entering the nozzle on the garment steamer head 100 during carrying, thereby improving the safety during carrying.

[0037] Working principle: When in use, the handle 101 is in a vertical state, and the garment steamer head 100 is in an unshielded protective state (such as Figure 6As shown), after use, when the handle 101 needs to be folded to shield the garment steamer head 100, the T-shaped rod 107 is first pressed backward. The T-shaped rod 107 compresses the first spring 108 backward and moves out of the cross-shaped limiting hole 109 into the circular box 105, releasing the fixation of the T-shaped rod 107, thereby releasing the fixation of the support shaft 104 and the handle 101. At this time, the handle 101 can be rotated upward. When the handle 101 is rotated upward to be level with the garment steamer head 100, the support shaft 104 drives the T-shaped rod 107 to rotate through the first rectangular groove 106, and then the pressing force on the T-shaped rod 107 is released. The elastic force of the first spring 108 in the compressed state drives the T-shaped rod 107 to move forward into the cross-shaped limiting hole 109. At this time, the cross-shaped limiting hole 109 restricts the T-shaped rod 107 again, thereby realizing the restriction and fixation of the handle 101. Then, the U-shaped handle can be pulled in the direction away from the protective cover 201. The U-shaped handle drives the first moving rod 207 and the second moving rod 213 to move through the connecting rod 209. The first moving rod 207 drives the first pressing block 205 to move. The first pressing block 205 compresses the first compression spring 208 and separates from the second elastic rubber sleeve 206, thereby releasing the fixation of the protective cover 201. When the moving rod 213 moves, it drives the second pressing block 211 to move and compresses the second compression spring 214. At this time, the protective cover 201 can be rotated and sleeved on the garment steamer head 100. Then, the tension on the U-shaped handle is relaxed. The elastic force of the first compression spring 208 in the compressed state drives the first pressing block 205 to move downward until it is in close contact with the second elastic rubber sleeve 206. Under the action of the friction between the first pressing block 205 and the second elastic rubber sleeve 206, the protective cover 201 is fixed. At the same time, the second compression spring 214 in the compressed state drives the second pressing block 211 and the second elastic anti-slip rubber downward to contact the first The top of an elastic non-slip rubber 212 is in close contact. Under the action of the friction between the first elastic non-slip rubber 212 and the second elastic non-slip rubber, the protective cover 201 and the garment steamer head 100 are fixed. The fixing force between the protective cover 201 and the garment steamer head 100 can further achieve the fixation between the garment steamer head 100 and the handle 101. At this time, the handle 101 is in a folded and fixed state, and the protective cover 201 is in a protective state for the garment steamer head 100. The folded protection can effectively reduce the entry of dust and impurities into the nozzle of the garment steamer head 100 during carrying, thereby improving the safety during carrying.

[0038] When it is used again, the U-shaped handle can be pulled again to release the fixation of the protective cover 201. At this time, the protective cover 201 can be rotated to separate from the hanging iron head 100. After separation, and when the protective cover 201 is rotated to a horizontal state, the pulling force on the U-shaped handle can be released, and the friction between the first pressing block 205 and the second elastic rubber sleeve 206 can be used to fix the protective cover 201. Then, the T-shaped rod 107 is pressed backward again to release the fixation of the handle 101. Then, the handle 101 is rotated downward to a vertical state. After rotating to a vertical state, the pressing force on the T-shaped rod 107 is released, so that the T-shaped rod 107 moves again into the cross-shaped limiting hole 109. The cross-shaped limiting hole 109 limits the T-shaped rod 107, thereby achieving the restricted fixation of the handle 101, and it can be used again.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
