Description

Technical Field

[0001] This invention relates to the field of fabric cleaning machine technology, and more particularly to a wastewater tank for a handheld fabric cleaning machine that suppresses wastewater splashing. Background Technology

[0002] During the cleaning process of the handheld fabric cleaner, high-pressure water jets first dissolve stains, followed by brush scrubbing, and then suction draws the wastewater into a wastewater tank, achieving efficient cleaning. The wastewater tank collects the dirty water generated during the cleaning process, preventing wastewater backflow or secondary pollution.

[0003] When the wastewater tank collects wastewater, the wastewater inside is easily agitated by airflow, and splashed wastewater can easily enter the motor of the handheld fabric washer through the air extraction port, causing damage to the motor. At the same time, in order to avoid damage to the motor caused by splashed wastewater, the effective volume of the wastewater tank is small, which affects the continuous cleaning ability of the handheld fabric washer. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater tank for a handheld fabric cleaning machine that suppresses wastewater splashing, thereby solving the problem of wastewater surging back and forth inside the tank and splashing into the motor, causing damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater tank for a handheld fabric cleaning machine that suppresses wastewater splashing, comprising:

[0006] The lower housing has two symmetrically arranged lower guide vane groups on both sides of its bottom surface. Each lower guide vane group includes at least two lower guide vanes, which are arranged in a figure-eight shape. A lower baffle is also provided on the bottom surface of the lower housing, and the lower baffle is located between the two lower guide vane groups.

[0007] The upper cover has one end rotatably mounted on the lower box and the opposite end is provided with a latch. The latch connecting shaft is rotatably connected to the lower box and the latch is rotatably mounted on the latch connecting shaft. The lower box end is provided with an abutment part for engaging with the latch. The upper cover is provided with parallel sewage channels and air extraction channels. The sewage channels are L-shaped and the air extraction channels are L-shaped.

[0008] The top surface of the upper cover is provided with a first upper baffle and a second upper baffle arranged in parallel. The sewage channel passes through the first upper baffle, and the air extraction channel passes through the second upper baffle. The bottom opening of the air extraction channel faces the first upper baffle. The position of the first upper baffle corresponds to the lower baffle. When the lower box and the upper cover are closed, the bottom surface of the first upper baffle contacts the top surface of the lower baffle. The first upper baffle has symmetrically arranged notches on both sides.

[0009] As a further description of the above technical solution:

[0010] The air extraction channel includes a vertical section and a bent section. The vertical section is perpendicular to the top surface of the upper cover, and the bottom of the bent section is inclined towards the bottom surface of the lower box.

[0011] As a further description of the above technical solution:

[0012] The lower box is made of transparent plastic.

[0013] As a further description of the above technical solution:

[0014] The upper cover is rotatably connected to the lower box via a pivot.

[0015] As a further description of the above technical solution:

[0016] A sealing ring groove is provided on the bottom surface of the upper cover, and the sealing ring is fixedly installed in the sealing ring groove.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the upper cover is provided with several first ribs.

[0019] As a further description of the above technical solution:

[0020] The lower box has a trapezoidal cross-section that is wider at the top and narrower at the bottom.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In this invention, for sewage entering the sewage tank, on the one hand, the sewage is blocked and dispersed to both sides of the sewage tank by two lower guide vane groups on the bottom surface of the lower tank. When the sewage surges back and forth due to airflow, the lower guide vanes effectively suppress the surge of water flow. Furthermore, when the sewage tank is closed, the first upper baffle and the lower baffle are in contact, further blocking the back and forth surge of sewage. On the other hand, by hiding the bottom opening of the air extraction channel between the first upper baffle and the second upper baffle, sewage is prevented from entering the air extraction channel along the inner wall of the sewage tank, thereby effectively preventing sewage from entering the motor through the air extraction channel. The sewage in the sewage tank is blocked and spaced by multiple barriers and intervals composed of the lower guide vane group, the lower baffle, the first upper baffle, and the second upper baffle, effectively solving the problem of sewage surging back and forth and splashing into the motor and causing damage. In addition, the tortuous sewage channel and air extraction channel on the upper cover, together with the first upper baffle and the second upper baffle, effectively prevent sewage from escaping.

[0023] 2. In this invention, since the first upper baffle and the lower baffle are attached when the sewage tank is closed, the notches on both sides of the first upper baffle and the gap between the lower baffle and the inner wall of the lower tank can ensure the speed at which sewage flows into the sewage tank and passes through the lower baffle and the first upper baffle, thus preventing sewage from flowing back from the sewage channel.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] Example 1

[0033] Please see Figure 1-2 This invention provides a technical solution: a wastewater tank for a handheld fabric cleaning machine that suppresses wastewater splashing, comprising:

[0034] The lower housing 1 has two symmetrically arranged lower guide vane groups on both sides of its bottom surface. Each lower guide vane group includes at least two lower guide vanes 11, which are arranged in a figure-eight shape. A lower baffle 12 is also provided on the bottom surface of the lower housing 1, and the lower baffle 12 is located between the two lower guide vane groups.

[0035] The upper cover 2 has one end rotatably mounted on the lower box 1 and the opposite end is provided with a latch 21. The latch connecting shaft 22 is rotatably connected to the lower box 1, and the latch 21 is rotatably mounted on the latch connecting shaft 22. The lower box 1 has an abutment part 13 at the end for engaging with the latch 21. The upper cover 2 is provided with a parallel sewage channel 23 and an air extraction channel 24. The sewage channel 23 is L-shaped and the air extraction channel 24 is L-shaped.

[0036] The top surface of the upper cover 2 is provided with a first upper baffle 25 and a second upper baffle 26 arranged in parallel. The sewage channel 23 passes through the first upper baffle 25, and the air extraction channel 24 passes through the second upper baffle 26. The bottom opening of the air extraction channel 24 faces the first upper baffle 25. The position of the first upper baffle 25 corresponds to the lower baffle 12. When the lower box 1 and the upper cover 2 are closed, the bottom surface of the first upper baffle 25 contacts the top surface of the lower baffle 12. The first upper baffle 25 is provided with symmetrically arranged notches 251 on both sides.

[0037] Since the first upper baffle 25 and the lower baffle 12 are in contact when the sewage tank is closed, the gaps 251 on both sides of the first upper baffle 25 and the gap between the lower baffle 12 and the inner wall of the lower tank 1 can ensure the speed at which sewage flows into the sewage tank and passes through the lower baffle 12 and the first upper baffle 25, thus preventing sewage from flowing back from the sewage channel 23.

[0038] The exhaust channel 24 includes a vertical section and a bent section. The vertical section is perpendicular to the top surface of the upper cover 2, and the bottom of the bent section is inclined towards the bottom surface of the lower box 1. The airflow passes through the bent section and the vertical section in sequence before exiting the sewage tank. The downward-sloping bent section is fixed to the second upper baffle 26. The inclined state of the bent section further prevents sewage from flowing out.

[0039] The lower casing 1 is a transparent plastic casing, making it easy to observe the amount of sewage inside. The upper casing 2 is similar.

[0040] The upper cover 2 is rotatably connected to the lower box 1 via a rotating shaft 27, thereby enabling the upper cover 2 to be rotated and installed.

[0041] The lower tank 1 has a trapezoidal cross-section that is wider at the top and narrower at the bottom, which further suppresses the surging of the sewage surface inside the lower tank 1. The shape of the upper cover 2 matches the shape of the lower tank 1.

[0042] Working principle: When the fabric cleaning machine is in use, the suction generated by the fan inside the main unit creates a vacuum inside the wastewater tank through the air extraction channel 24 at the top of the upper cover 2. Wastewater enters the wastewater tank through the wastewater channel 23 of the upper cover 2 and is stored in the lower tank 1, while the airflow is discharged through the air extraction channel 24 at the top of the upper cover 2.

[0043] For sewage entering the sewage tank, on the one hand, the two lower guide vanes on the bottom surface of the lower tank 1 block and disperse the sewage to both sides of the sewage tank. When the sewage surges back and forth due to airflow, the lower guide vanes effectively suppress the surge of water flow. In the closed state of the sewage tank, the first upper baffle 25 and the lower baffle 12 are in contact, further blocking the back and forth surge of sewage. On the other hand, by hiding the bottom opening of the air extraction channel 24 between the first upper baffle 25 and the second upper baffle 26, sewage is prevented from entering the air extraction channel 24 along the inner wall of the sewage tank, thereby effectively preventing sewage from entering the motor through the air extraction channel 24. The sewage in the sewage tank is blocked and spaced by the lower guide vane group, the lower baffle 12, the first upper baffle 25, and the second upper baffle 26, which effectively solves the problem of sewage surging back and forth and splashing into the motor and causing damage. In addition, the tortuous sewage channel 23 and air extraction channel 24 on the upper cover 2, together with the first upper baffle 25 and the second upper baffle 26, effectively prevent sewage from escaping.

[0044] Example 2

[0045] Based on the above embodiments, this embodiment further improves upon the following technical solution: a sealing ring groove is provided on the bottom surface of the upper cover 2, and the sealing ring 28 is fixedly installed in the sealing ring groove.

[0046] When the upper cover 2 is rotated to close, the upper cover 2 and the lower box 1 are closed by the latch 21 engaging with the upper abutment part 13 of the lower box 1, and the sealing ring 28 improves the sealing of the sewage tank to prevent sewage leakage.

[0047] Example 3

[0048] Based on the above embodiments, this embodiment further improves upon the following technical solution: the inner wall of the upper cover 2 is provided with several first ribs 29.

[0049] The first rib 29 improves the deformation resistance of the upper cover 2 and ensures the airtightness of the sewage tank. It also further prevents sewage from entering the exhaust channel 24 along the inner wall of the sewage tank. Similarly, a second rib can be provided on the inner wall of the lower tank 1.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
