Description

Technical Field

[0001] This utility model relates to a structural improvement of a handheld steam brush, particularly a water tank disassembly 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] To facilitate water refilling and prevent water from entering the main body, some handheld steam brushes feature detachable water tanks. When water needs to be added, the locking mechanism is released, allowing the tank to be removed for easy access. However, this tank design requires users to perform multiple steps when refilling, such as pressing buttons or rotating specific parts. This not only wastes time and effort but also easily frustrates users, especially when they are in a hurry to iron clothes; the complicated operation significantly reduces the user experience.

The center block has a groove, in which a water inlet and an air vent needle protrude. The water inlet is aligned with the water inlet of the smart seat, and the air vent needle is aligned with the air return hole. The water inlet is connected to a water pump via a water pipe. Symmetrical locking holes are provided on the left and right end faces of the center block, each with an upper and lower inclined surface. A locking opening is provided on the wall of the center block groove. Symmetrical locking blocks are provided within the positioning block, each with a triangular lock head at its inner end. The triangular lock head has an upper and lower inclined surface, and a spring is provided at the outer end of the locking block. The spring drives the triangular lock head to extend from the locking opening, thereby engaging the locking holes on both ends of the center block. The structure of the smart seat and air return hole adopts a common existing design and will not be elaborated further here.

[0008] In a preferred embodiment, the lower end of the main body is provided with a main body end cap, and the positioning block and positioning block groove are located on the main body end cap; the main body end cap is provided with a locking block slide groove, and the locking block is slidably disposed on the locking block slide groove.

[0009] The lock block structure is optimized such that the spring is located in the lock block groove, and a spring sleeve is provided on the rear side of the lock block. The front end of the spring is fixed on the spring sleeve, and the rear end of the spring presses against the main body end cover.

[0010] To improve the handling feel of the water tank assembly, the water tank assembly has rows of grooves on its side.

[0011] The water inlet of the water tank is concealed and located on the central block, with an openable rubber stopper. The water inlet is hidden on the upper surface of the water tank, resulting in a more aesthetically pleasing appearance with no protruding parts on the steam brush.

[0012] In a preferred embodiment of a return air hole, a reset soft membrane is covered on the return air hole. The reset soft membrane normally seals the return air hole, and the reset soft membrane is opened when the air hole puncture needle is inserted into the return air hole.

[0013] In a preferred embodiment of a smart seat, the smart seat has an insertion cavity in the middle, a water channel is provided on the side wall of the insertion cavity, a sealing ball is slidably disposed in the insertion cavity, and a return spring is provided below the sealing ball. The return spring presses the sealing ball upward, thereby sealing the water inlet with the sealing ball.

[0014] To facilitate water intake, the bottom of the water inlet has a cross-shaped inlet that will not be completely blocked by the sealing ball, thus preventing water from flowing through.

[0015] When using this utility model, the water tank needs to be filled with water. Then, the water tank assembly is installed into the lower end of the main body from bottom to top. In the initial stage of installation, the positioning block is gradually inserted into the positioning block groove. The outer side of the positioning block is limited by the edge, and a central block is also inserted in the middle to strengthen the positioning. The two sides of the central block push the lower inclined surface of the triangular lock head, causing the lock block to retract inward until the triangular lock head slides to the locking hole position and locks into the locking hole, thus completing the fixation of the entire water tank assembly to the main body.

[0016] When you need to disassemble the water tank, simply pull the water tank down. The inclined surface on the water tank's locking hole presses against the inclined surface on the lock head, causing the locking block to retract inward. The water tank assembly can then be easily separated to perform the water filling operation.

[0017] The beneficial effects of this utility model are as follows: 1. The handle of the handheld steam brush does not use a locking mechanism with a button or latch when connecting to the water tank. Instead, it uses a direct insertion and extraction method for unlocking. The symmetrically arranged triangular locking blocks with upper and lower bevels ensure the connection strength and allow for easy removal of the water tank. Eliminating the unlocking process results in a significantly improved user experience. 2. The locking holes are located on the symmetrical sides of the central block. The central block can be made thicker, increasing structural strength and resistance to deformation. Compared to locking holes located on the edges, this reduces the deformation interference of external forces on the locking block and related structures, enhancing the stability of the connection. 3. The smart seat and vent allow the connected water pump to easily draw water from the water tank, preventing the water from being blocked by air pressure. The water tank is located at the bottom of the main body, and the lower center of gravity makes the handheld steam brush more stable during use, making full use of the space at the bottom of the handheld steam brush body.
