[0020] The embodiment of the present application provides a handheld pool cleaner, which is used to solve the technical problem that when the existing handheld pool cleaner is in use, it is relatively laborious for the user to push under the buoyancy of water, affecting the user experience.

[0021] In order to make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] Please refer to Figures 1 to 4 The embodiment of the present application provides a handheld pool cleaner, including a body 100 and a floor brush 200. A filter chamber 110 and a drainage chamber 120 are provided in the inner cavity of the body 100. The filter chamber 110 is connected to the floor brush 200. A drive motor 300 is installed above the drainage chamber 120. A drainage impeller 400 connected to the drive motor 300 is installed in the drainage chamber 120. The drainage impeller 400 is provided with circumferentially distributed arc-shaped blades 410. A plurality of drainage ports 121 are provided on both sides of the drainage chamber 120, and the orientation of the drainage ports 121 is inclined upward.

[0023] In this embodiment, the inner cavity of the body 100 is successively a filter chamber 110 and a drainage chamber 120 from top to bottom. The filter chamber 110 is connected to the floor brush 200 through a connecting pipe. The filter chamber 110 and the drainage chamber 120 are in a communicating state. A drive motor 300 is hermetically installed above the drainage chamber 120. A drainage impeller 400 connected to the drive motor 300 is provided in the drainage chamber 120. A water suction port 420 is provided at the bottom of the drainage impeller 400, and multiple circumferentially distributed arc-shaped blades 410 are in the middle. Driven by the drive motor 300, the drainage impeller 400 can suck water, flow through the floor brush 200, pass through the filter chamber 110 for filtration, and then flow to the drainage chamber 120 and be discharged through the drainage ports 121. Since the orientation of the drainage ports 121 is inclined upward, the water flows upward after passing through the drainage ports 121 when discharged, and a downward force is formed at the drainage chamber 120 when discharged, so that the cleaner has a downward force to resist the buoyancy in the water. Therefore, it is relatively labor-saving for the user to push the cleaner for cleaning, which is convenient for use.

[0024] Further, the top of the drain opening 121 is a drain wall 1211, and the drain walls 1211 are all arranged to slope upward; a plurality of drain openings 121 of the washing machine are all provided on both sides of the washing machine. The drain walls 1211 at the tops of the drain openings 121 are integrally inclined, so that the orientation of the drain openings 121 is inclined upward; when the water flows out, it is discharged obliquely upward, making it more labor-saving to use.

The housing 130 is sleeved on the mounting frame 140, and the drain opening 121 is opened on the mounting frame 140; further, a filter cavity 110 is formed in the inner cavity of the mounting frame 140. A water guide wall 141 is provided at the top of the mounting frame 140, and a partition plate 500 is erected on the top of the water guide wall 141 to form the drain cavity 120 between the partition plate 500 and the housing 130; the water guide wall 141 is formed by extending upward from the upper end surface of the mounting frame 140 and is respectively provided on the front and rear sides of the washing machine. A drain cavity 120 is formed in the middle. A mounting space for components such as the drive motor 300 is formed by the partition plate 500 erected above the water guide wall 141. Under the partition of the partition plate 500, a drain cavity 120 is formed between the water guide wall 141 and the housing 130. When the drain impeller 400 operates, the water can be better guided to the drain opening 121, accelerating the drainage efficiency.

[0026] Further, the water guide walls 141 are provided on both sides of the drain impeller 400; the middle part of the water guide walls 141 is in an arc shape matching the drain impeller 400, and both sides are inclined and extend towards the edge of the drain opening 121; the middle parts of the water guide walls 141 on both sides of the drain cavity 120 are both arc-shaped recessed towards the edge, matching the drain impeller 400. The other two side walls of the water guide walls 141 extend outwardly inclined to the edge of the drain opening 121, so that inclined side walls are formed on both sides of the drain cavity 120. After the drain impeller 400 guides the water, the water flow can directly flow towards the drain opening 121 under the limitation of the water guide wall 141. While accelerating the drainage efficiency, due to the limitation of the space in the drain cavity 120, the acting force during drainage can be further strengthened, making the washing machine more labor-saving to use.
