Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment components, and more specifically, to a liquid mixing device and a cleaning equipment. Background Technology

[0002] In existing technologies, cleaning equipment such as floor scrubbers, robotic vacuum cleaners, and fabric cleaning machines typically rely on a solution of detergent and water to achieve effective cleaning. However, the mixing effect of detergent and water directly affects cleaning efficiency and user experience. Current solutions generally employ three interfaces on the equipment housing: a detergent inlet, a water tank inlet, and a liquid outlet, using a simple flow path structure to mix the detergent and water. However, in practical use, this type of structure often suffers from uneven fluid dynamics or an unreasonable mixing path design, leading to insufficient mixing, unstable detergent concentration, localized residue, or incomplete cleaning.

[0003] Therefore, it is urgent to optimize the mixing flow path inside the cleaning equipment to improve the mixing efficiency and uniformity of the cleaning agent and water, so as to achieve a more stable and efficient cleaning effect. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, the embodiments of this utility model propose a liquid mixing device, which uses baffles to separate the shell space, thereby achieving efficient and uniform mixing of cleaning agent and clean water. The device has a compact structure and is easy to manufacture, effectively improving the cleaning effect and equipment performance.

[0005] This utility model embodiment also proposes a cleaning device having the above-mentioned liquid mixing device.

[0006] The technical solution adopted by this utility model is: to provide a liquid mixing device, including a shell, with a baffle plate and a baffle column inside the shell. The baffle plate divides the interior of the shell into two regions: a mixing chamber and an annular cavity. The liquid inlet and water inlet are both connected to the annular cavity, and the baffle column is disposed in the mixing chamber.

[0007] This invention utilizes internal baffles to divide the housing space into a mixing chamber and an annular cavity, effectively guiding the liquid flow path and enhancing fluid agitation. Both the liquid inlet and water inlet are connected to the annular cavity, ensuring continuous and thorough mixing of the fluid. This significantly improves upon the problems of insufficient mixing and unstable concentration in existing technologies, avoiding localized residues and incomplete cleaning. Furthermore, the device has a compact structure, simple manufacturing process, and is easy to apply in industrial settings, effectively improving the performance of cleaning equipment and enhancing the user experience.

[0008] According to one embodiment of this utility model, the housing includes an upper shell and a lower shell, which are combined and connected to form a closed cavity. This design improves the housing's sealing performance, prevents liquid leakage, and ensures a stable and reliable mixing process.

[0009] According to one embodiment of this utility model, a turbulence column is disposed on the inner wall of the upper shell, and a turbulence rib is disposed on the lower shell. The separate arrangement of the turbulence column and the turbulence rib effectively enhances the turbulence effect within the shell, promoting improved mixing efficiency.

[0010] According to one embodiment of the present invention, the lower shell is provided with a mounting groove, which, together with the inner sidewall of the lower shell, forms an annular groove. The mounting groove is used to fix the liquid mixing device in a pre-installation position.

[0011] According to one embodiment of this utility model, a sealing ring is provided between the upper shell and the lower shell. This effectively prevents liquid leakage during the mixing process and ensures the sealing performance of the device.

[0012] According to one embodiment of the present invention, the upper shell and the lower shell are connected by snap fasteners, UV welding, or ultrasonic welding.

[0013] According to one embodiment of this invention, the diameter of the liquid inlet connector is smaller than that of the water inlet connector, and the flow velocity of the liquid inlet connector is greater than that of the water inlet connector. This enhances fluid mixing within the annular cavity through the jet effect, improving mixing uniformity and efficiency.

[0014] According to one embodiment of this invention, multiple flow-disrupting columns are arranged at sharp angles along the inflow direction of the annular cavity. This reduces flow resistance, optimizes the fluid path, and promotes sufficient turbulence and mixing of the fluid.

[0015] According to one embodiment of this utility model, the mating protrusion of the upper shell is provided with reinforcing ribs. This improves the rigidity of the upper shell structure and enhances the durability and stability of the overall device.

[0016] In another embodiment, a cleaning device is disclosed, including the liquid mixing device described above. Attached Figure Description

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0031] like Figure 1-8 As shown, this embodiment discloses a liquid mixing device, including a housing with a baffle plate 25 and a baffle column 14 inside. The baffle plate 25 divides the internal space of the housing into two regions: a mixing chamber 26 and an annular cavity. The annular cavity is formed by sealing the upper opening of an annular groove 24. The mixing chamber 26 is used for liquid mixing, while the annular cavity serves as a space for further mixing and agitation of the liquid. Both the liquid inlet connector 21 and the water inlet connector 22 are connected to the annular cavity, ensuring that the cleaning agent and clean water can enter the annular cavity simultaneously, forming the initial conditions for multi-fluid confluence.

[0032] The turbulence column 14 is located within the mixing chamber 26. Its main function is to physically obstruct and guide the fluid, generating turbulence and fluid disturbance, significantly improving the mixing intensity and uniformity of the liquid, and preventing the cleaning agent from stratifying or exhibiting uneven concentrations before exiting the liquid. The turbulence ribs 25 effectively divide the shell space, rationally guide the fluid path, and enhance the circulation and stirring effect of the fluid within the mixing chamber 26 and the annular cavity, thereby improving the overall mixing efficiency.

[0033] The housing includes an upper shell 1 and a lower shell 2, which are connected to form a closed cavity to ensure sealing during liquid mixing and prevent leakage. Fluid-dispersing columns 14 are disposed on the inner wall of the upper shell 1, while fluid-dispersing ribs 25 are disposed on the inner side of the lower shell 2, distributed in different parts of the housing to reduce manufacturing difficulty. The lower shell 2 has a mounting groove 23, which, together with the inner wall of the lower shell 2, forms an annular groove 24.

[0034] The upper shell 1 is recessed inward to form a mating protrusion 13. The mounting groove 23 abuts against the mating protrusion 13 to form an annular cavity, ensuring a robust structure and stable fluid passage. A sealing ring 3 is provided between the upper shell 1 and the lower shell 2 to improve sealing performance and effectively prevent leakage during liquid mixing. The upper shell 1 and the lower shell 2 can be connected in various ways, such as by snap-fit ​​11, UV welding, or ultrasonic welding.

[0035] Furthermore, in this embodiment, the upper shell 1 is provided with buckles 11 on both sides, and the lower shell 2 is provided with locking posts 27 on both sides corresponding to the buckles 11. The buckles 11 are elastically deformed so that the locking grooves on them can be engaged with the locking posts 27, thereby realizing the buckle 11 connection between the upper shell 1 and the lower shell 2.

[0036] The orifice diameter of the liquid inlet connector 21 is smaller than that of the water inlet connector 22, resulting in a higher flow velocity at the liquid inlet connector 21 than at the water inlet connector 22. This creates a jet effect, which is beneficial for shearing and mixing of the liquid within the annular cavity. Multiple turbulence columns 14 are arranged at sharp angles to reduce fluid resistance and promote smooth fluid flow and thorough mixing. The mating protrusions 13 inside the upper shell 1 are equipped with reinforcing ribs to enhance the overall structural rigidity, prevent deformation due to fluid impact or mechanical vibration, and ensure the service life and reliability of the device.

[0037] Furthermore, in this embodiment, multiple turbulence columns 14 are arranged in a triangular interval, with one corner facing the opening of the turbulence rib plate 25, that is, towards the inflow direction of the annular cavity.

[0038] Overall, this liquid mixing device has a compact structure and a reasonable internal fluid channel design. Through the combined action of the baffle 25 and the baffle column 14, it significantly improves the mixing effect of the cleaning agent and water, avoiding the defects of insufficient mixing, unstable concentration and local residue in the prior art. It improves the cleaning efficiency of the cleaning equipment and the user experience. Moreover, the manufacturing process is simple. The upper shell 1 and the lower shell 2 are formed by an integral process, which is convenient for industrial production and application promotion.
