Description

TECHNICAL FIELD

[0002] In the field of commercial cleaning equipment, a conventional automatic blowdown form is to set a ball valve in the middle of a blowdown pipeline, and to realize blowdown and flow interception by opening and closing the ball valve. The sewage in the blowdown pipeline is easy to mix with sand, and the valve body is easy to contain sand during the opening and closing process of the ball valve, which causes the valve body to wear out, and eventually causes the ball valve to leak in the closed state or even cannot be closed. In addition, the minimum diameter of the blowdown pipeline is limited by the diameter of the ball valve, and the smaller the diameter, the more likely it is to cause the blowdown pipeline to be blocked, that is, the diameter of the ball valve limits the diameter of the blowdown pipeline, thereby causing the blowdown pipeline to be blocked.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

Figure 3 The front view of the pinch valve in the closed state provided by an embodiment of the present disclosure is shown.

Figure 6 The structure of the intercepting device provided by another embodiment of the present disclosure is shown. Figure 7 The front view of the pinch valve in the open state provided by another embodiment of the present disclosure is shown. Figure 8 The front view of the pinch valve in the closed state provided by another embodiment of the present disclosure is shown. Figure 9 The rear view of the pinch valve in the closed state provided by an embodiment of the present disclosure is shown. As shown in the figure, Figures 1 to 9 The pinch valve 10 includes a support 100, a driving member 200, a connecting rod 300, a swing arm 400, at least one sleeve 500, and a clamping member 600.

[0031] The pinch valve 10 is configured to open or pinch the hose 41 to enable or not enable the liquid in the hose 41 to flow. Exemplarily, the water flow direction F in the hose 41 is from top to bottom. The water flow direction F can be vertically downward, or from top to bottom in a direction that forms an acute angle with the vertical direction.

[0032] Exemplarily, the support 100 can be a plate structure, a block structure, a bracket, etc., and the shape of the support 100 is not limited in the present disclosure. The driving member 200 is fixedly connected or rotatably connected with the support 100. The first end of the connecting rod 300 is rotatable relative to the support 100 about the first axis L1. The driving member 200 is in transmission connection with the connecting rod 300, so that the connecting rod 300 is rotated about the first axis L1 under the driving of the driving member 200. Exemplarily, the connection mode of the driving member 200 and the support 100 can be selected according to actual needs. Exemplarily, the driving member 200 is rotatably connected with the support 100, and the first end of the connecting rod 300 is rotatably connected with the support 100 about the first axis L1. Exemplarily, the driving member 200 is fixedly connected with the support 100, and the first end of the connecting rod 300 is rotatably connected with the driving member 200 about the first axis L1. Exemplarily, transmission connection refers to the process of transmitting power from one component to another component through different transmission mechanisms in mechanical movement. Transmission is usually achieved through shafts, gears, belts, chains, etc., and the purpose is to transmit power from a power source to a driven component to achieve mechanical movement. Exemplarily, the shape of the connecting rod 300 can be a rod shape, a plate shape, or a special shape, as long as the connecting rod 300 achieves the function of a connecting rod. The shape of the connecting rod 300 is not limited in the present disclosure.

[0033] The first end of the swing arm 400 is fixedly connected or rotatably connected with the second end of the connecting rod 300. The at least one sleeve 500 is rotatably connected with the second end of the swing arm 400 about the second axis L2. The second axis L2 is parallel to the first axis L1. The shape of the swing arm 400 can be a rod shape, a plate shape, or a special shape, and the shape of the swing arm 400 is not limited in the present disclosure. The connection mode of the first end of the swing arm 400 and the second end of the connecting rod 300 can be set according to actual needs. Exemplarily, in the case where the pinch valve 10 includes one sleeve 500, the first end of the swing arm 400 is fixedly connected with the second end of the connecting rod 300. Exemplarily, in the case where the pinch valve 10 includes multiple sleeves 500, the first end of the swing arm 400 is rotatably connected with the second end of the connecting rod 300.

[0034] The clamping piece 600 is connected with the support piece 100 and is arranged adjacent to the sleeve 500, and the hose 41 is located between the sleeve 500 and the clamping piece 600. Exemplarily, the clamping piece 600 can be plate-shaped or block-shaped, as long as it can provide clamping force to the hose 41, and the shape of the clamping piece 600 is not limited in the present disclosure.

[0035] Under the driving of the driving piece 200, the connecting rod 300 drives the swing arm 400 to rotate around the first axis L1, and the swing arm 400 drives the sleeve 500 to approach or move away from the clamping piece 600, so that the pipe clamping valve 10 is in an open state or a clamping state. In the process of the sleeve 500 approaching the clamping piece 600, the sleeve 500 rotates around the second axis L2 relative to the second end of the swing arm 400, and the sleeve 500 rolls relative to the outer wall of the hose 41, that is, the sleeve 500 performs tangential motion relative to the outer wall of the hose 41, so that in the process of the sleeve 500 gradually approaching the clamping piece 600, the sand and stones in the hose 41 can be pushed to move in the water flow direction F, thereby reducing the probability of the sleeve 500 clamping the sand and stones, reducing the probability of water leakage when the pipe clamping valve 10 is in the clamping state, and prolonging the service life of the pipe clamping valve 10. In addition, the pipe diameter of the hose 41 is no longer limited by the diameter of the ball valve, and the user can set the diameter of the hose 41 according to the needs, thereby reducing the probability of sewage blockage.

[0036] In some embodiments, the number of sleeves 500 is multiple, the multiple sleeves 500 are arranged in parallel, and the first end of the swing arm 400 is rotatably connected with the second end of the connecting rod 300. As shown in Figure 3 , when the pipe clamping valve 10 is in the clamping state, the reserved gap δ between the multiple sleeves 500 and the clamping piece 600 is equal, so that the multiple sleeves 500 and the clamping piece 600 clamp the hose 41 at the same time, which provides multiple guarantees for flow cutting and further improves the reliability of clamping.

[0037] In some embodiments, as shown in Figure 5 , when the pipe clamping valve 10 is in the clamping state, the reserved gap δ between the sleeve 500 and the clamping piece 600 is less than or equal to twice the wall thickness t of the hose, so as to ensure that the hose 41 is tightly pressed and prevent water leakage.

[0038] In some embodiments, as shown in Figure 3 , the pipe clamping valve 10 further comprises a first elastic piece 710. The first end of the first elastic piece 710 is connected with the connecting rod 300, and the second end of the first elastic piece 710 is connected with the swing arm 400. When the pipe clamping valve 10 is in the clamping state, the multiple sleeves 500 are symmetrically arranged relative to the orthographic projection of the end face of the sleeve 500 on the first elastic piece 710. Exemplarily, the first end of the swing arm 400 is rotatably connected with the second end of the connecting rod 300 around a third axis L3. As shown in Figure 1 and Figure 2As shown in FIG. 6, when the pinch valve 10 is in the open state, the first elastic member 710 is located on the side of the third axis L3 close to the hose 41. As shown in FIG. 7, Figure 3 As shown in FIG. 8, the two sleeves 500 are symmetrically arranged relative to the first elastic member 710 in the end face projection of the sleeve 500, and the first elastic member 710 passes through the third axis L3 when the pinch valve 10 is in the clamping state.

[0039] In actual application, as shown in FIG. 9, Figure 1 and Figure 2 As shown in FIG. 6, when the pinch valve 10 is in the open state, the pinch valve 10 may be subjected to vibration, and the swing arm 400 may rotate around the third axis L3 due to the vibration, thereby driving the sleeve 500 to rotate counterclockwise, so that the sleeve 500 is located on the side of the third axis L3 away from the hose. If the sleeve 500 is located on the side of the third axis L3 away from the hose, when the driving member 200 drives the connecting rod 300 to rotate around the first axis L1, the connecting rod 300 drives the swing arm 400 to rotate around the first axis L1, and the swing arm 400 drives the sleeve 500 to move towards the clamping member 600, if the swing arm 400 rotates around the third axis L3, it may cause the pinch valve 10 to fail to achieve the clamping state. By arranging the first elastic member 710, the swing arm 400 can be prevented from rotating around the third axis L3 under the action of vibration, so that the sleeve 500 is always located on the side of the third axis L3 close to the hose when the pinch valve 10 is in the open state, avoiding the pinch valve 10 failing to achieve the clamping state, and further improving the clamping reliability of the pinch valve 10.

[0040] In some embodiments, as shown in FIG. 10, Figure 5 The driving member 200 includes a linear driving member 210. The linear driving member 210 includes a first fixed member 211 and a telescopic member 212 connected with each other, the first fixed member 211 is rotatably connected with the support member 100, and the telescopic member 212 is rotatably connected with the connecting rod 300. The telescopic member 212 is telescopic under the drive of the first fixed member 211, so as to drive the connecting rod 300 to rotate around the first axis L1. As an example, the linear driving member 210 can be an electric push rod, a pneumatic cylinder or other mechanism that can realize linear driving. As an example, when the telescopic member 212 is retracted, the pinch valve 10 is in the clamping state; when the telescopic member 212 is extended, the pinch valve 10 is in the open state. When the telescopic member 212 is retracted, the connecting rod 300 is substantially perpendicular to the hose 41, which facilitates the pinch valve 10 to remain in the clamping state. When the pinch valve 10 is in the clamping state, even if the linear driving member 210 is powered off, the telescopic member 212 will remain in the retracted state, so that the pinch valve 10 remains in the clamping state, which can prevent the pinch valve 10 from clamping failure.

[0041] In some embodiments, as shown in FIG. 10, Figure 6As shown, the driving member 200 comprises a rotating driving member 220. The rotating driving member 220 comprises a second fixing member 221 and a rotating member 222 connected with each other, the second fixing member 221 is fixedly connected with the support member 100, and the rotating member 222 is connected with the first end of the connecting rod 300, the second fixing member 221 drives the rotating member 222 to rotate, so that the rotating member 222 drives the connecting rod 300 to rotate around the first axis L1. The rotating driving member 220 can be a steering engine, a rotating cylinder or other mechanism that can realize rotating driving. The rotating driving member 220 directly drives the connecting rod 300 to rotate around the first axis L1, and the structure is simple.

[0042] In some embodiments, as shown in the drawings, Figure 6 As shown, in the case that the driving member 200 comprises the rotating driving member 220, the second end of the connecting rod 300 has a first shaft hole 301, and the pinch valve 10 further comprises a connecting shaft 720 and a second elastic member 730. The connecting shaft 720 is fixedly connected with the first end of the swing arm 400, and the connecting shaft 720 penetrates into the first shaft hole 301. The first end of the second elastic member 730 is connected with the support member 100 or the second fixing member 221, and the second end of the second elastic member 730 is connected with the connecting shaft 720.

[0043] The first axis L1 has a first point in the orthogonal projection on the plane perpendicular to the first axis L1, and the second axis L2 has a second point in the orthogonal projection on the plane perpendicular to the first axis L1, when the pinch valve 10 is in the open state, the orthogonal projection of the second elastic member 730 on the plane perpendicular to the first axis L1 is located on the first side of the line connecting the first point and the second point; when the pinch valve 10 is in the clamping state, the orthogonal projection of the second elastic member 730 on the plane perpendicular to the first axis L1 is located on the second side of the line connecting the first point and the second point, so that when the rotating driving member 220 is powered off when the pinch valve 10 is in the clamping state, the second elastic member 730 can be tightened to prevent the swing arm 400 from swinging, thereby ensuring that the pinch valve 10 is in the clamping state and preventing the pinch valve 10 from clamping failure.

[0044] In some embodiments, as shown in the drawings, Figures 6 to 8 As shown, the pinch valve 10 further comprises an abutting member 740. The abutting member 740 is fixedly connected with the support member 100 and abuts against the connecting shaft 720, and the orthogonal projection of the abutting member 740 on the plane perpendicular to the first axis L1 is located on the second side of the line connecting the first point and the second point, thereby limiting the position of the connecting shaft 720 when the pinch valve 10 is in the clamping state, preventing the swing arm 400 from swinging too much, and ensuring that the pinch valve 10 is in the clamping state.

[0045] In some embodiments, as shown in the drawings, Figure 5As shown, the second end of the swing arm 400 has a shaft portion 410 extending along a second axis L2. The pinch valve 10 further comprises a bushing 750. The bushing 750 is sleeved on the outer side of the shaft portion 410, and the sleeve 500 is sleeved on the outer side of the bushing 750, so that the rotation of the bushing 750 relative to the shaft portion 410 is more flexible.

[0046] Figure 10 Fig. 1 shows a structural schematic diagram of a cleaning device according to an embodiment of the present disclosure. Figure 11 Fig. 2 shows a structural schematic diagram of a cleaning device according to another embodiment of the present disclosure. An embodiment of the present disclosure further provides a flow interception device 20. As shown in Fig. 2, Figure 1 and Figure 11 As shown, the flow interception device 20 is configured to achieve interception of a first pipe 42 and a second pipe 43. The flow interception device 20 comprises the pinch valve 10 in the above embodiment and a hose 41. The hose 41 is arranged between the sleeve 500 and the clamping member 600 of the pinch valve 10, and two ends of the hose 41 are respectively in communication with the first pipe 42 and the second pipe 43.

[0048] Since the flow interception device 20 comprises the pinch valve 10, the flow interception device 20 has all the technical features and technical effects of the pinch valve 10, which will not be described here again.

[0049] An embodiment of the present disclosure further provides a cleaning device 1. As shown in Fig. 1, Figure 10 and Figure 11 As shown, the cleaning device 1 comprises a sewage tank 30 and a sewage pipe 40. Exemplarily, the cleaning device 1 can be a cleaning robot, a scrubber, or the like. Exemplarily, the sewage tank 30 is used to contain sewage, which can contain sand and stones.

[0050] A first end of the sewage pipe 40 is in communication with the sewage tank 30, and a liquid in the sewage pipe 40 flows from the first end of the sewage pipe 40 to a second end of the sewage pipe 40, Figure 10 The water flow direction F is shown by arrows. The vertical height of the first end of the sewage pipe 40 is greater than the vertical height of the second end of the sewage pipe 40, so that the water flow direction is from high to low. Exemplarily, the sewage pipe 40 can be vertically arranged or arranged at an acute angle with the vertical direction. For example, the sewage pipe 40 is arranged at an angle of 45 degrees or 60 degrees with the vertical direction.

[0051] As shown in Fig. 1, Figure 10As shown, in the case where the sewer pipe 40 includes the hose 41, the cleaning device 1 further includes the pinch valve 10 in the above-described embodiments. The pinch valve 10 is connected with the hose 41 and is configured to open or pinch the hose 41.
