Description

Technical Field

[0001] This utility model relates to an improvement of a steam brush steam output structure. Background Technology

[0002] A handheld steam brush is a convenient garment care tool that greatly helps people solve the problem of wrinkles in their clothes in daily life.

[0003] This handheld steam brush contains a water tank, pump, and steam generator. Its compact size and lightweight design make it easy to carry and store. Whether used at home or while traveling or on business trips, it can be easily packed into your luggage for convenient clothing care anytime.

[0004] The working principle of a handheld steam brush is based on the conversion of electrical energy into heat energy, which in turn heats water into steam. When the user connects the power and turns on the switch, the current passes through the heating element, which rapidly heats the water in the tank to boiling. Once the water turns into steam, it is sprayed onto the surface of the clothing through the steam nozzle under pressure. The high-temperature steam causes the clothing fibers to expand and soften, at which point the user can easily smooth out wrinkles by simply pulling the clothing gently.

[0005] However, existing handheld steam brushes require a corresponding steam generator mold. The number of steam holes at the front end of the steam generator corresponds to the number of holes at the front end of the steam generator. A connecting block with a through hole in the middle connects the two together. This results in a steam generator having to be designed separately for each steam brush, which increases the production cost of the steam brush. Utility Model Content

[0006] To overcome the shortcomings of current steam brushes that require a steam generator, this invention provides a steam brush with an adaptive steam nozzle structure.

[0007] The technical solution of this utility model to solve its technical problem is: a steam brush with an adaptive steam nozzle structure, comprising a main body with a handle in the middle, a brush head above the handle, and a water tank below the handle; a steam generator is provided in the brush head, the steam generator consisting of a generator body and a top cover; a partition is provided inside the generator body, the partition enclosing a labyrinthine passage within the inner cavity of the generator body, and a heating tube is embedded in the generator body; the labyrinthine passage in the steam generator includes an inner labyrinthine passage and an outer labyrinthine passage, the end point of the outer labyrinthine passage being located at the front end of the generator body, a steam outlet being located at the front end, a main steam outlet being located at the front end of the generator body, and the steam outlet being connected to the main steam outlet; the starting point of the inner labyrinthine passage... A water inlet is provided at the point where the end of the inner maze path is connected to the beginning of the outer maze path. An ironing panel is provided on the front side of the brush head, and a steam distribution block is provided on the inner side of the ironing panel. A distribution cavity is recessed on the front face of the steam distribution block, and a connecting hole is opened on the rear face of the steam distribution block to connect to the distribution cavity. The main steam outlet is engaged in the connecting hole, and a first protrusion is protruding in the connecting hole. The first protrusion seals and fixes the main steam outlet. A ring of outer fixing edge of the distribution block is protruding on the rear face of the ironing panel, and a ring of second protrusion is protruding on the outer side of the steam distribution block. The shape of the outer fixing edge of the distribution block is consistent with that of the steam distribution block, so that the steam distribution block is just engaged in the outer fixing edge of the distribution block. The second protrusion seals and fixes the side of the steam distribution block. The ironing panel is provided with steam nozzles, which are connected to the distribution chamber; The steam generator is fixed to the brush head housing, and the ironing panel has fixing posts on both sides of the rear end face. The fixing posts are fixed to the brush head housing, and the fixing points of the fixing posts are located on the left and right sides of the steam generator; thus, the ironing panel presses the steam distribution block onto the front end face of the steam generator.

[0008] A method for connecting the main body of a steam generator to its upper cover; the upper end of the partition of the steam generator is provided with a riveting end, and the upper cover of the steam generator is provided with a riveting groove, wherein the riveting end is riveted into the riveting groove.

[0009] Furthermore, the partition plate is also integrally provided with a number of riveting posts, and the upper cover is provided with riveting holes, with the upper ends of the riveting posts riveted into the riveting holes.

[0010] To improve the dispersion performance of the steam ejected from the brush head, the steam nozzle is an hourglass-shaped steam nozzle that is narrow in the middle and wide on both sides.

[0011] To improve the overall aesthetics of the brush head, the ironing panel is also provided with several pseudo steam nozzles, which are not connected to the distribution chamber.

[0012] To reduce the volume of the steam distribution block, the middle part of the steam distribution block is enlarged, and the connecting hole is located at the enlarged part.

[0013] The steam generator is optimized by providing several water-blocking steps in the labyrinth channel of the steam generator. The water-blocking steps include an inner water-blocking step, a middle water-blocking step, an outer water-blocking step, and a tail-end water-blocking step. The inner water-blocking step is located on the inner labyrinth channel, the middle water-blocking step is located at the connection between the inner labyrinth channel and the outer labyrinth channel, the outer water-blocking step is located on the outer labyrinth channel, and the tail-end water-blocking step is located on both sides of the steam outlet on the outer labyrinth channel.

[0014] To improve the stability of the steam generator, a heat-insulating foot is provided at the lower end of the steam generator, and the heat-insulating foot is positioned on the brush head housing.

[0015] To facilitate connection to the steam distribution block, the steam generator is square and has a flat front end.

[0016] Furthermore, a temperature control unit and a thermal protection unit are provided on the lower side of the generator body. The temperature control unit and the thermal protection unit are for better monitoring of the steam generator's status, while the thermal protection unit is a fuse mechanism that prevents further damage in case the steam generator malfunctions and overheats.

[0017] In use, our steam generator is a universal modular unit. When the ironing panel on the front side of the brush head has a number of steam nozzles, we can design and produce corresponding steam distribution blocks according to the actual situation. Thus, we can easily achieve the functions of different styles of steam brushes by changing the mold of this steam distribution block. Alternatively, when the ironing panel has pseudo-steam nozzles, we can reduce material and mold costs by reducing the volume of the steam distribution block. The principle of the steam generator and steam brush involved in this application is the same as that of the existing ones, and will not be repeated here.

[0018] The beneficial effects of this utility model are as follows: 1. The universal steam generator with a single main steam outlet can be adapted to various steam brush designs. When developing new steam brush styles, manufacturers do not need to redesign complex steam generation systems and can easily integrate the universal steam generator into new designs by matching different steam distribution blocks according to different product requirements. This reduces R&D costs and time, meets diverse market demands, improves production efficiency, and reduces errors and costs in the production process. 2. The ironing panel uses hourglass-shaped steam nozzles that are narrow in the middle and wide on both sides. These hourglass-shaped steam nozzles allow the airflow to converge at the narrowest point of the nozzle and then be ejected in a funnel shape, reducing the maximum range of the steam airflow and preventing burns from excessive steam. Furthermore, the steam dispersion is stronger, and the steam reaches the clothing more evenly. 3. The steam generator has four sets of water-blocking steps, which can effectively prevent liquid water from flowing out of the steam outlet. The riveting end and riveting column at the upper end of the generator body can effectively increase the connection strength between the generator body and the top cover. The front end has only one large steam outlet instead of a small steam outlet with the same number of steam nozzles, so the air passage is less likely to be blocked, thereby improving the service life of the steam brush product.

[0032] To improve the dispersion performance of the steam ejected from the brush head 2, the steam nozzle 22 is an hourglass-shaped steam nozzle that is narrow in the middle and wide on both sides.

[0033] To improve the overall aesthetics of the brush head 2, the ironing panel 15 is also provided with several pseudo steam nozzles 29, which are not connected to the distribution chamber 17.

[0034] In order to reduce the volume of the steam distribution block 16, the middle part of the steam distribution block 16 is enlarged, and the connecting hole 18 is provided at the enlarged part.

[0035] The steam generator 4 is optimized, and the maze passage 8 of the steam generator 4 is provided with several water-blocking steps 30. The water-blocking steps 30 include an inner water-blocking step 31, a middle water-blocking step 32, an outer water-blocking step 33, and a tail-end water-blocking step 34.

[0041] This embodiment is used in the same way as Embodiment 1, and will not be described again here.

[0042] The beneficial effects of this utility model are as follows: 1. The universal steam generator with a single main steam outlet can be adapted to various steam brush designs. When developing new steam brush styles, manufacturers do not need to redesign complex steam generation systems and can easily integrate the universal steam generator into new designs by matching different steam distribution blocks according to different product requirements. This reduces R&D costs and time, meets diverse market demands, improves production efficiency, and reduces errors and costs in the production process. 2. The ironing panel uses hourglass-shaped steam nozzles that are narrow in the middle and wide on both sides. These hourglass-shaped steam nozzles allow the airflow to converge at the narrowest point of the nozzle and then be ejected in a funnel shape, reducing the maximum range of the steam airflow and preventing burns from excessive steam. Furthermore, the steam dispersion is stronger, and the steam reaches the clothing more evenly. 3. The steam generator has four sets of water-blocking steps, which can effectively prevent liquid water from flowing out of the steam outlet. The riveting end and riveting column at the upper end of the generator body can effectively increase the connection strength between the generator body and the top cover. The front end has only one large steam outlet instead of a small steam outlet with the same number of steam nozzles, so the air passage is less likely to be blocked, thereby improving the service life of the steam brush product.
