Description

A control valve and a fabric cleaning machine Technical Field

[0001] This utility model relates to the field of fabric cleaning machines, specifically to a control valve and a fabric cleaning machine. Background Technology

[0002] A fabric cleaning machine is a specialized device for cleaning various fabric items. It uses high-pressure jet technology to spray a mixture of detergent and water onto the stains to dissolve and remove them. Then, through brushing and suction, the mixture of stains and water is drawn into a wastewater tank, leaving the fabric dry and clean. Fabric cleaning machines are highly effective for cleaning various fabric items such as carpets, upholstered furniture, cushions, pet beds, and window seat cushions. They are simple and convenient to operate, quickly and effectively completing the cleaning process.

[0003] Fabric cleaning agents include a cleaning brush head, which contains a control valve to regulate the water spray. Currently, ensuring more even water distribution during prolonged use is a critical issue that needs to be addressed. Summary of the Invention

[0004] To solve at least one technical problem of the prior art, this utility model provides a control valve and a fabric cleaning machine.

[0005] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is: a control valve, including a valve body and a valve core, wherein the valve body is provided with an inlet flow channel, an outlet flow channel, and a first cavity and a second cavity that are interconnected. The first cavity is connected to the outlet flow channel, and the second cavity is connected to the inlet flow channel. The second cavity is provided with an outlet diversion component, which causes the water in the inlet flow channel to be evenly distributed and then flow to the outlet flow channel.

[0006] In some embodiments, the diverter is a block-shaped structure protruding from the bottom wall of the second cavity.

[0007] In some embodiments, there is a gap between the outer wall of the block structure and the cavity wall of the second cavity.

[0008] In some embodiments, the top surface of the block structure is provided with a downwardly recessed diversion groove, which communicates with the first cavity;

[0009] The block structure has a through hole on its end face facing the liquid inlet channel that communicates with the diversion groove.

[0010] In some embodiments, the cross-section of the diversion channel is T-shaped or rectangular.

[0011] In some embodiments, the diverter is integrally formed into the second cavity or detachably fixed to the bottom wall of the second cavity.

[0012] In some embodiments, the valve core is movably disposed within the first cavity, and the wall surface of the diverter facing the valve core is on the same plane as the cavity wall of the first cavity.

[0013] In some embodiments, the length of the outlet channel is greater than the length of the inlet channel.

[0014] A fabric cleaning machine includes the aforementioned control valve.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] The control valve of this invention has a flow divider in the second cavity. The flow divider can make the water in the inlet channel evenly distributed and flow to the outlet channel, thereby making the water output of the control valve more uniform. At the same time, the length of the outlet channel of this invention is greater than the length of the inlet channel, which can suppress the pressure change at the outlet end of the outlet pipe, further making the water output of the control valve more uniform.
