Description

Technical Field

[0001] This utility model relates to the field of fabric making machine technology, and more specifically, to a liquid mixing device and a fabric making machine. Background Technology

[0002] A textile cleaning machine is a device used for surface cleaning of textiles. Currently, most textile cleaning machines on the market mainly consist of a housing, a water pump, an air pump, a steam generator, a clean water tank, a waste water tank, a negative pressure fan, and a cleaning head. The water pump, air pump, steam generator, and negative pressure fan are all installed inside the housing. The clean water tank and waste water tank are connected to the upper part of the housing. The steam generator is connected to the water pump and air pump, the water pump is connected to the clean water tank, and the negative pressure fan is connected to the waste water tank. The cleaning head is connected to the clean water tank and waste water tank via pipelines. When the textile cleaning machine is working, the water pump draws water from the clean water tank to the steam generator, the air pump delivers compressed air to the steam generator, and the steam generator delivers steam through pipelines to the cleaning head. The steam sprayed from the cleaning head cleans the surface of the textiles. Meanwhile, when the negative pressure fan is working, it creates negative pressure in the wastewater tank, allowing water vapor or liquid water from cleaning the textile surface to be drawn into the wastewater tank. To improve the effectiveness of the fabric cleaning machine in cleaning textile surfaces, users often add cleaning solution to the clean water tank. Currently, users manually add cleaning solution to the clean water tank during fabric machine use. However, manually adding cleaning solution has the following problems: 1. If too little cleaning solution is added, the cleaning effect on the textile surface will be poor; 2. If too much cleaning solution is added, the foam generated by the cleaning solution can be drawn into the negative pressure fan, which will eventually cause an odor during fabric machine use. Therefore, there is an urgent need for a liquid mixing device that can automatically mix the clean water and cleaning solution in the fabric machine in a specific ratio. Utility Model Content

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] See Figure 1-3As shown in the figure, this application discloses a liquid mixing device, including an upper cover 1 and a lower cover 2; the upper cover 1 is connected to the upper end of the lower cover 2, and a liquid mixing chamber 3 is formed between the upper cover 1 and the lower cover 2; the top of the upper cover 1 is provided with at least two liquid inlets 11, and the bottom of each liquid inlet 11 is provided with at least one through hole 12, each through hole 12 is used to connect the liquid mixing chamber 3 and the corresponding liquid inlet 11, and the diameter of the through hole 12 at the bottom of each liquid inlet 11 is different from each other; the bottom of the upper cover 1 is connected with a one-way valve 4 corresponding to each liquid inlet 11, and each one-way valve 4 is used to block the through hole 12 at the bottom of the corresponding liquid inlet 11; the lower cover 2 is provided with a liquid outlet 20 communicating with the liquid mixing chamber 3; in this embodiment, the above-mentioned liquid inlet is an open-end structure with an open top, and the open-end liquid inlet can be directly connected to a bottle or barrel containing liquid so that the liquid in the bottle or barrel flows into the corresponding liquid inlet.

[0024] Each one-way valve 4 is made of soft rubber material and includes a valve plate 41 and a valve stem 42. The valve stem 42 is vertically positioned at the middle of the upper end of the valve plate 41 and is connected to the upper cover 1. The valve plate 41 is tightly attached to the outer bottom surface of the upper cover 1 and is used to block the through hole 12 at the bottom of the corresponding liquid inlet 11. By adopting this structure of one-way valve, the connection between the valve stem and the upper cover allows the one-way valve to be reliably assembled with the upper cover. When a negative pressure is generated inside the liquid mixing chamber, the valve plate can bend downward, that is, the valve plate can release the blockage at the bottom of the through hole. At this time, the liquid from each liquid inlet can flow through the valve. Liquids can flow into the liquid mixing chamber through the through holes at the bottom of each liquid inlet, and the liquids entering the liquid mixing chamber can be mixed in the liquid mixing chamber; when the negative pressure state in the liquid mixing chamber disappears, the valve plate can rebound under the action of the rebound force and stick tightly to the outer bottom surface of the top cover to block the through holes; in this embodiment, there are two liquid inlets, one of which has several through holes at the bottom, and these several through holes are all located inside the valve plate in the circumferential direction on the corresponding one-way valve. In addition, the diameter of these several through holes is larger than the diameter of the through hole at the bottom of the other liquid inlet.

[0025] Each liquid inlet 11 has a socket 13 at its bottom, and the valve stem 42 of each one-way valve 4 is inserted into the corresponding socket 13 from bottom to top. Each valve stem 42 has an annular groove 421 on its outer side wall. The annular groove 421 engages with the edge of the socket 13 and seals it circumferentially. With this structure, after the valve stem is inserted into the socket, the annular groove can engage with the edge of the socket and seal it circumferentially. This allows the one-way valve to be reliably and conveniently assembled with the top cover, and prevents liquid inside the liquid inlet from flowing into the liquid mixing chamber through the gap between the valve stem and the socket.

[0026] Each valve stem 42 has an annular conical surface 422 on its upper outer wall. The annular conical surface 422 is used to guide the valve stem 42 into the socket 13 by engaging with the wall of the socket. Under the action of the annular conical surface, when the valve stem is engaged with the socket, the annular conical surface can guide the valve stem into the socket by engaging with the wall of the socket, which facilitates the assembly of the one-way valve and the top cover.

[0027] The bottom surface of the liquid mixing chamber 3 is formed into a slope, and the liquid outlet 20 is located at the lowest point of the bottom surface of the liquid mixing chamber 3. By setting the bottom surface of the liquid mixing chamber as a slope, each liquid can be automatically mixed as it flows into the liquid mixing chamber and towards the liquid outlet. The mixed liquid can then reliably flow out through the liquid outlet to avoid the mixed liquid remaining in the liquid mixing chamber.

[0028] The bottom inner surface of the lower cover 2 is provided with an annular rib 21, and the bottom outer surface of the upper cover 1 is provided with an annular slot 14. The upper end of the annular rib 21 is inserted into the annular slot 14 and is tightly sealed to the annular slot 14. The liquid mixing chamber 3 is formed inside the annular rib 21. With this structure, after the upper cover and the lower cover are assembled, the upper end of the annular rib can be inserted into the annular slot and tightly sealed to the annular slot. Since the liquid mixing chamber is formed inside the annular rib, the sealing performance of the liquid mixing chamber can be guaranteed. In addition, in order to improve the sealing performance of the liquid mixing chamber, glue can be filled into the annular slot so that the glue can further seal the gap between the annular rib and the annular slot.

[0029] The outer side wall of the upper cover 1 is provided with several inverted buckles 15 circumferentially, and the outer side wall of the lower cover 2 is provided with spring buckles 22 corresponding to the inverted buckles 15 one by one. Each spring buckle 22 cooperates with the inverted buckle 15 at the corresponding position to lock the upper cover 1 and the lower cover 2. With this structure, when the upper cover and the lower cover are assembled, each spring buckle can cooperate with the inverted buckle at the corresponding position, so as to facilitate the assembly of the upper cover and the lower cover.

[0030] A fabric weaving machine includes the aforementioned liquid mixing device. When the liquid mixing device is applied to the fabric weaving machine, one liquid inlet is connected to the bottom of a clean water tank in the machine, and the other liquid inlet is connected to the bottom of a cleaning liquid tank in the machine. Since the apertures of the through holes at the bottom of each liquid inlet are different, when a water pump connected to the liquid outlet draws a mixture of clean water and cleaning liquid, the clean water and cleaning liquid can enter the liquid mixing chamber in a set ratio and mix (the ratio of clean water and cleaning liquid entering the liquid mixing chamber is preset according to the aperture size of the through holes). This avoids the need for manual mixing of clean water and cleaning liquid, providing convenience to the user and preventing the addition of too little or too much cleaning liquid, thus improving the accuracy of the water-to-cleaning-liquid ratio.

[0031] Example 2

[0032] See Figure 4 As shown, unlike Embodiment 1, the upper end of each liquid inlet 11 is a closed structure, and the side wall of the upper cover 1 is provided with a liquid inlet interface 16 corresponding to each liquid inlet 11. Each liquid inlet interface 16 is connected to the liquid inlet 11 at the corresponding position. In this embodiment, each liquid inlet interface can be connected to different liquid inlet pipes, so that the liquid in the liquid inlet pipe used to transport different liquids can enter different liquid inlets.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
