Description

Technical Field

[0001] This utility model relates to an improvement in the structure of a steam brush, and in particular to an improvement in the anti-leakage structure of a water pump. Background Technology

[0002] Handheld steam brushes typically heat water in a tank using an internal steam generator. Once the water reaches its boiling point, it produces high-temperature steam. This steam is then transported from the generator to the nozzle and evenly sprayed out. The high-temperature steam softens and expands the fabric fibers, allowing for easy removal of wrinkles when combined with stretching and smoothing motions.

[0003] The steam passage contains high-pressure steam, making it the least safe part of the entire steam brush.

[0004] To minimize the distance of the steam channel, modern handheld steam brushes often place the steam generator near the steam nozzle on the brush head. The steam generator requires a water pump to deliver room-temperature water to produce steam. We typically place the water tank at the bottom and the water pump closest to the water tank.

[0005] To reduce size, modern handheld steam brushes are designed with a folding function. However, because the water pump hose has poor elasticity, folding the hose can cause it to move, which can lead to hose detachment and leakage at some hose joints after prolonged use. Utility Model Content

[0006] To overcome the shortcomings of current handheld folding steam brushes that are prone to leakage at the water pump pipe interface, this utility model provides a handheld folding steam brush that is not prone to leakage at the water pump connector.

[0007] The technical solution of this utility model to solve its technical problem is as follows: a handheld folding steam brush with a water pump connector that is not prone to leakage, including a brush head with a handle, a water tank detachably provided at the lower end of the handle, a rotatable joint provided at the upper end of the handle, and a water pump provided in the handle; an installation plate is also provided inside the lower side of the handle, and a component cavity is provided below the installation plate; a surrounding wall protrudes above the installation plate, the surrounding wall forming a water pump installation chamber, the inner side of the water pump installation chamber is smooth; a side shell is provided on the outer side of the water pump, the outer surface of the side shell is smooth, and a positioning block is provided on the side shell; a limiting groove is opened on the surrounding wall, and an inlet is provided at the upper end of the limiting groove to facilitate the entry of the positioning block; the water pump is located in the water pump installation chamber, the positioning block is limited in the limiting groove, and the water pump can move up and down a certain distance; the water outlet of the water pump is located above the water pump, and a water outlet pipe is provided on the water outlet through the rotatable joint.

[0008] A preferred embodiment of the side shell is a U-shaped side shell, and both the side shell and the mounting plate are made of plastic.

[0009] For ease of movement, both the side shell and the mounting plate are made of ABS material.

[0010] In a preferred embodiment of the mounting plate fixing method, the mounting plate is provided with fixing ears on both sides, the fixing ears are provided with fixing holes, and mounting plate fixing screws are provided in the fixing holes to fix the mounting plate to the handle housing.

[0011] Further optimization of the component cavity structure: the main conductive wire port of the steam brush is located on the rear side of the component cavity below the mounting plate, and the main conductive wire enters the component cavity from the main conductive wire port. The mounting plate is provided with a PCB board clip protruding into the component cavity.

[0012] To facilitate the positioning and fixing of the main conductive wire, the mounting plate is provided with a wire slot in front of the main conductive wire opening, and the main conductive wire is locked in the wire slot.

[0013] To further enhance the reinforcement effect, the wire slot has screw holes on both sides of the PCB board, and a clamp is installed on the screw holes to clamp the main conductive wire.

[0014] To facilitate power supply to the water pump, the mounting plate has a cable tray in the connecting element cavity to facilitate the passage of the water pump power supply line.

[0015] A preferred embodiment of a limiting groove and a surrounding wall, wherein the surrounding wall is a square surrounding wall and the limiting groove is located at a corner of the surrounding wall.

[0016] When used, this utility model is similar to the existing handheld folding steam brush. When the steam brush folds and moves the water pipe, it generally does not move the water pump up and down. However, when the water pipe ages and causes high stress at the water pump outlet, the water pump will move in the water pump installation chamber to relieve the pressure on the water pipe, thereby reducing the risk of the water pipe coming off at the interface.

[0017] The beneficial effects of this utility model are as follows: 1. The water pump can move up and down within the pump installation chamber. When the water pipe ages and generates high stress at the pump outlet, the pump can alleviate the pressure on the water pipe by moving. This design greatly reduces the possibility of the water pipe coming off at the interface, ensuring the normal operation of the steam brush, suppressing water leakage and circuit failures caused by water pipe detachment, and improving the service life of the steam brush. 2. A component cavity is set below the pump mounting plate, leading the main conductive wire of the steam brush into the component cavity. This layout makes full use of the internal space of the steam brush, making the overall structure more compact. The rational arrangement of various components and circuits within a limited space helps to reduce the size of the steam brush, making it easier to carry and store. Attached Figure Description
