Description

Technical Field

[0001] The present invention relates to the technical field of alkali water production devices, in particular to an alkali water production device for hydrogen production. Background Art

[0002] The hydrogen production system generates hydrogen through the electrolysis of alkaline water, typically a potassium hydroxide solution. The electrolytic tank is connected to the alkaline water production unit, which is then connected to a reverse osmosis water purification unit. After tap water passes through the reverse osmosis water purification unit, purified water is output from the reverse osmosis water purification unit and enters the alkaline water production unit. Potassium hydroxide powder is then manually poured into the alkaline water production unit and mixed with the purified water from the alkaline water production unit to form alkaline water. The alkaline water then enters the electrolytic tank for electrolysis.

[0003] The existing alkaline water making device includes a cylinder, a reverse osmosis water purification device is connected to the cylinder and inputs pure water into the cylinder, and a stirring device is provided in the cylinder. When potassium hydroxide powder is poured into the cylinder from the upper end of the cylinder manually, the stirring device stirs the alkaline water in the cylinder to accelerate the dissolution of potassium hydroxide. In this process, when the stirring device is stirring, some alkaline water is likely to splash out from the upper end of the cylinder and injure people. Summary of the Invention

[0004] In order to solve the shortcoming of the existing alkali water making device that is easy to splash, the present invention proposes an alkali water making device for hydrogen production to avoid splashing.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for producing alkaline water for hydrogen production includes a cylinder and a water pump. The lower end of the cylinder is provided with a discharge port, a water inlet and a water outlet. The discharge port is connected to a discharge pipe, and the discharge pipe is provided with a valve. The water pump and the water inlet are connected by a first pipe, and the water pump and the water outlet are connected by a second pipe. Alkaline water is provided in the cylinder, and a water inlet pipe passes through one side of the cylinder. The water outlet of the water inlet pipe is arranged below the liquid level of the alkaline water. A filter is provided in the cylinder, and the edge of the filter is arranged along the inner circumference of the cylinder. The filter is arranged below the liquid level of the alkaline water. A discharge port is provided on the upper side of the cylinder.

[0007] Through the above-mentioned arrangement, splashing of alkaline water is avoided during the process of making alkaline water, thereby improving safety. Specifically, the discharge pipe is used to output alkaline water to the electrolytic tank, and the valve is used to control the output of alkaline water. When making alkaline water, the raw material (potassium hydroxide powder) is poured into the cylinder from the discharge port by manpower, and the raw material enters the alkaline water and begins to dissolve. The reverse osmosis water purification device is connected to the water inlet pipe and transports pure water to the cylinder through the water inlet pipe. The water inlet pipe is arranged below the liquid level of the alkaline water to prevent the alkaline water from splashing. In addition, in order to speed up the dissolution rate of the raw material, the water pump is operated, and the alkaline water in the cylinder passes through the water outlet, the water outlet pipe, the water pump, the water inlet pipe and the water inlet back to the cylinder, thereby increasing the flow of the alkaline water in the cylinder, thereby increasing the dissolution rate of the raw material. In addition, the water outlet and the water inlet are both arranged below the liquid level of the alkaline water. When the alkaline water is output from the water inlet, no splashing is formed. The arrangement of the filter can prevent impurities in the raw material from entering the electrolytic tank. The filter is arranged in the cylinder, so that it is convenient to clean the filter. Specifically, when cleaning the filter, the liquid level of the alkaline water can be lowered so that the filter is above the liquid level, and then the filter is cleaned. During cleaning, the cylinder can continue to output alkaline water to the electrolytic tank without affecting hydrogen production. When the cleaning is completed, pure water continues to be transported into the cylinder so that the liquid level of the alkaline water rises to the upper side of the filter, and then raw materials are poured into the cylinder to continue to produce alkaline water.

[0008] Furthermore, the water inlet pipe is arranged on the upper side of the filter.

[0009] Through the above arrangement, the dissolution rate of the raw materials can be further accelerated. The filter divides the space of the cylinder into a first space and a second space. The first space is arranged above the filter, and the second space is arranged below the filter. When the raw materials are poured into the cylinder, the raw materials are located in the first space, and the raw materials are dissolved in the alkaline water in the first space and slowly penetrate into the alkaline water in the second space. The concentration of the alkaline water in the first space is greater than the concentration of the alkaline water in the second space. When the water inlet pipe is arranged on the upper side of the filter, the water inlet pipe outputs pure water to the first space, which can help reduce the concentration of the alkaline water in the first space, thereby accelerating the dissolution rate of the raw materials in the first space.

[0010] Furthermore, a base is provided on the lower side of the cylinder, a ladder is provided on the upper side of the base, and the cylinder and the base are fixedly connected by a first connecting frame.

[0011] The above arrangement makes it easier for humans to dump the raw materials. In reality, the raw materials are all packed in snakeskin bags, which need to be cut when dumping. Then, workers need to climb up the ladder and pour the raw materials in the snakeskin bags into the cylinder from the discharge port.

[0012] Furthermore, a support ring is slidably connected to the inner side of the cylinder, the support ring is arranged along the inner circumference of the cylinder, a support rod is fixedly connected to the inner side of the support ring, and a rotating shaft extending vertically is fixedly connected to the middle part of the support rod. The axis of the rotating shaft coincides with the axis of the cylinder, and the filter is in the shape of a trumpet with a larger upper part and a smaller lower part. The outer periphery of the filter is connected to the support ring, and the inner periphery of the filter is connected to the rotating shaft. The alkali water production device for hydrogen production also includes a rotating device for driving the support to rotate around the axis of the rotating shaft, and the discharge port is arranged above one side of the filter.

[0013] The above-mentioned arrangement can prevent the raw materials from clumping on the filter, thereby increasing the speed of raw material dissolution. Specifically, the filter is trumpet-shaped, so that the surface area of the filter is larger. When the raw materials are deposited on the filter, the raw materials are "distributed" more widely, that is, the thickness of the raw materials is smaller, and the raw materials can be dissolved faster. In addition, the discharge port is set above one side of the filter. When the raw materials are poured in, the raw materials fall to one side of the filter and begin to dissolve. Under the action of the rotating device, the filter rotates around the axis of the rotating shaft, so that the raw materials poured from the discharge port can fall to different positions of the filter, so that the filter can receive the raw materials, thereby making the raw materials on the filter more uniform and preventing the raw materials on the filter from clumping. The support ring and the rotating shaft are used to support the filter, and the rotating device drives the filter to rotate by driving the rotating shaft.

[0014] Furthermore, the rotating device includes a plurality of blades, which are arranged in a circular array with the axis of the rotating shaft as the center. The water outlet of the water inlet pipe is close to the blades and biased to one side of the rotating shaft to drive the blades and the rotating shaft to rotate.

[0015] Through the above arrangement, the pure water output from the water inlet pipe impacts the blades, thereby driving the rotation of the shaft.

[0016] Furthermore, the water inlet pipe and the cylinder are slidably connected, and the alkali water making device for hydrogen production also includes a first driving device for driving the water inlet pipe to move along the axis of the water inlet pipe, and a second driving device for driving the rotating shaft to move along the axis of the rotating shaft.

[0017] The above arrangement facilitates the cleaning of the filter. Specifically, when the filter needs to be cleaned, the water inlet pipe moves toward the outside of the cylinder under the action of the first drive device, thereby preventing interference between the water inlet pipe and the support ring. Then, under the action of the second drive device, the support ring moves upward and moves to the upper side of the water inlet pipe. At this time, the filter is located above the liquid surface of the alkaline water. Then, under the action of the first drive device, the water inlet pipe approaches the filter. At this time, the water inlet pipe is close to the upper edge of the filter. After the water inlet pipe inputs pure water, the pure water will impact the lower side of the filter, and part of the pure water will penetrate the filter and reach the upper side of the filter. It should be noted that most of the impurities on the filter are attached to the upper side of the filter. The pure water passing through the filter will knock the impurities attached to the upper side of the filter off the filter. Then, as the pure water moves along the filter toward the rotating shaft, the trumpet-shaped filter plays the role of collecting impurities. That is, under the action of the pure water, the impurities are flushed out of the filter and collected in the concave part of the filter. In addition, the water outlet of the water inlet pipe is biased to one side of the rotating shaft, so when the pure water output from the water inlet pipe hits the lower side of the filter, it will drive the filter to rotate around the axis of the rotating shaft. During the rotation of the filter, the circumferential impurities of the filter are all cleaned to the concave part of the filter, that is, the end of the filter close to the rotating shaft. Finally, the personnel can use a spoon to clean up the impurities in the concave part of the filter through the discharge port.

[0018] After cleaning is completed, under the action of the first driving device, the water inlet pipe moves away from the rotating shaft again, thereby preventing the support ring from interfering with the water inlet pipe when moving downward. Then, under the action of the second driving device, the rotating shaft, support ring, and filter move downward, and the support ring moves back to the lower side of the water inlet pipe. Then, under the action of the first driving device, the water inlet pipe approaches the rotating shaft. At this time, the filter returns to the alkaline water, and alkaline water production can be started again.

[0019] Furthermore, a connecting plate is fixedly connected to the inside of one end of the water inlet pipe near the rotating shaft, and the connecting plate is arranged at the lower side of the water inlet pipe. The connecting plate is rotatably connected to a water guide plate, which extends horizontally toward the blades. A return spring is arranged between the water guide plate and the connecting plate, and a first slide groove is provided on the lower side of the water inlet pipe. A slider is slidably connected in the first slide groove, and the upper end of the slider abuts the lower side of the water guide plate. The opposite sides of the upper end of the slider are fixedly connected to limiting protrusions, and the limiting protrusions abut the inner wall of the water inlet pipe. A second slide groove is provided on one side of the cylinder, and the water inlet pipe passes through the second slide groove and is slidably connected to the second slide groove. The lower end of the slider is provided with an inclined surface for driving the slider to move upward, and the inclined surface is at least partially arranged on the outside of the first slide groove.

[0020] The above arrangement can further increase the efficiency of cleaning the filter. Specifically, during the process of making alkali water, the water guide plate extends horizontally, and the pure water output from the water inlet pipe can directly impact the blades, thereby effectively driving the rotation of the shaft. When the filter screen needs to be cleaned, under the action of the first driving device, the water inlet pipe moves away from the rotating shaft, the inclined surface approaches the second chute, the lower side of the second chute squeezes the inclined surface and makes the slider move upward, and the slider pushes the water guide plate to rotate upward. When the water guide plate rotates upward, the return spring twists, and the return spring applies torsion to the water guide plate, thereby making the water guide plate squeezed on the slider. When the support ring moves to the upper side of the water inlet pipe, the water inlet pipe rotates towards the filter screen under the action of the first driving device and is close to the filter screen. At this time, the inclined surface and the second chute are abutted against one end of the rotating shaft. At this time, the water guide plate is inclined. Specifically, the end of the water guide plate close to the filter screen is tilted upward, so that when pure water is output from the water inlet pipe, the pure water is tilted to impact the filter screen under the action of the water guide plate. The direction of pure water movement is more perpendicular to the filter screen (not truly vertical, it can still drive the filter screen to rotate), so that more pure water can penetrate the filter screen, making it easier for impurities attached to the filter screen to be impacted off. When the filter screen is cleaned and the alkaline water is made again, the water guide plate is extended horizontally again under the action of the reset spring, and the limiting protrusion prevents the slider from falling out of the first chute.

[0021] Furthermore, a second connecting frame is fixedly connected to the upper side of the first connecting frame, and the first driving device includes a rack fixedly connected to the water inlet pipe, a gear fixedly connected to the rack, and a first motor for driving the gear to rotate, and the first motor is arranged on the second connecting frame.

[0022] Through the above arrangement, the water inlet pipe can be driven to move along the axial direction of the water inlet pipe. When the first motor drives the gear to rotate, the gear drives the water inlet pipe to move along the axial direction of the water inlet pipe through the rack.

[0023] Furthermore, the second driving device includes a sliding seat arranged on the upper side of the cylinder, a slide rail fixedly connected to the upper side of the cylinder, a second motor arranged at the upper end of the slide rail, and a screw rod extending vertically connected to the second motor, the screw rod passes through the sliding seat and is threadedly connected to the sliding seat, the upper end of the rotating shaft is inserted into the sliding seat and rotatably connected to the sliding seat, the upper end of the rotating shaft is fixedly connected to the sliding seat, and a limiting groove adapted to the annular protrusion is provided in the sliding seat, and the annular protrusion is rotatably connected in the limiting groove.

[0024] Through the above arrangement, the rotating shaft can be driven to move along the axis of the rotating shaft. Specifically, the second motor drives the screw to rotate, and the screw and the sliding seat rotate relative to each other, thereby driving the sliding seat to move up and down. Under the action of the annular protrusion, the sliding seat will not move relative to the rotating shaft in the up and down directions, so the sliding seat will drive the rotating shaft to move up and down, that is, the rotating shaft moves along the axis direction of the rotating shaft.

[0030] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0031] See also Figures 1 to 5 A device for making alkaline water for hydrogen production includes a cylinder 11 and a water pump 12. The lower end of the cylinder 11 is provided with a discharge port 111, a water inlet 112 and a water outlet 113. The discharge port 111 is connected to a discharge pipe 1111, and the discharge pipe 1111 is provided with a valve 1112. The water pump 12 and the water inlet 112 are connected by a first pipe 1121, and the water pump 12 and the water outlet 113 are connected by a second pipe 1131. Alkali water is provided in the cylinder 11, and a water inlet pipe 114 passes through one side of the cylinder 11. The water outlet 113 of the water inlet pipe 114 is provided below the liquid level of the alkaline water. A filter screen 115 is provided in the cylinder 11, and the edge of the filter screen 115 is provided along the inner circumference of the cylinder 11. The filter screen 115 is provided below the liquid level of the alkaline water. A discharge port 116 is provided on the upper side of the cylinder 11.

[0032] The above arrangement can avoid splashing of alkaline water during the alkaline water production process, thereby improving safety. Specifically, the discharge pipe 1111 is used to output alkaline water to the electrolytic tank, and the valve 1112 is used to control the output of the alkaline water. When making alkaline water, the raw material (potassium hydroxide powder) is poured into the cylinder 11 from the discharge port 116 by human labor. The raw material enters the alkaline water and begins to dissolve. The reverse osmosis water purification device is connected to the water inlet pipe 114 and transports pure water to the cylinder 11 through the water inlet pipe 114. The water inlet pipe 114 is set below the liquid level of the alkaline water to prevent the alkaline water from splashing. In addition, in order to speed up the dissolution rate of the raw material, the water pump 12 is operated, and the alkaline water in the cylinder 11 passes through the water outlet 113, the water outlet pipe, the water pump 12, the water inlet pipe 114 and the water inlet 112 to return to the cylinder 11, thereby increasing the flow of the alkaline water in the cylinder 11 and further increasing the dissolution rate of the raw material. In addition, the water outlet 113 and the water inlet 112 are both set below the liquid level of the alkaline water. When the alkaline water is output from the water inlet 112, no splashing occurs. The setting of the filter 115 can prevent impurities in the raw material from entering the electrolytic tank. The filter screen 115 is arranged in the cylinder 11, so as to facilitate the cleaning of the filter screen 115. Specifically, when cleaning the filter screen 115, the liquid level of the alkaline water can be lowered so that the filter screen 115 is located above the liquid level, and then the filter screen 115 is cleaned. During cleaning, the cylinder 11 can continue to output alkaline water to the electrolytic tank without affecting hydrogen production. When the cleaning is completed, pure water continues to be transported into the cylinder 11 so that the liquid level of the alkaline water rises to the upper side of the filter screen 115, and then raw materials are poured into the cylinder 11 to continue to produce alkaline water.

[0033] As an implementation method, the water inlet pipe 114 is arranged on the upper side of the filter screen 115.

[0034] Through the above-mentioned arrangement, the dissolution rate of the raw materials can be further accelerated. The filter 115 divides the space of the cylinder 11 into a first space and a second space. The first space is arranged above the filter 115, and the second space is arranged below the filter 115. When the raw materials are poured into the cylinder 11, the raw materials are located in the first space. The raw materials are dissolved in the alkaline water in the first space and slowly penetrate into the alkaline water in the second space. The concentration of the alkaline water in the first space is greater than the concentration of the alkaline water in the second space. When the water inlet pipe 114 is arranged on the upper side of the filter 115, the water inlet pipe 114 outputs pure water to the first space, which can help reduce the concentration of the alkaline water in the first space, thereby accelerating the dissolution rate of the raw materials in the first space.

[0035] As an implementation method, a base 13 is provided on the lower side of the cylinder 11 , a ladder 131 is provided on the upper side of the base 13 , and the cylinder 11 and the base 13 are fixedly connected via a first connecting frame 132 .

[0036] The above arrangement makes it convenient for manpower to dump the raw materials. In reality, the raw materials are all contained in snakeskin bags, which need to be cut when dumping. Then, personnel climb up the ladder 131 and pour the raw materials in the snakeskin bags into the cylinder 11 from the discharge port 116.

[0037] As an implementation method, a support ring 14 is slidably connected to the inner side of the cylinder 11, and the support ring 14 is arranged along the inner circumference of the cylinder 11. A support rod 141 is fixedly connected to the inner side of the support ring 14, and a rotating shaft 142 extending vertically is fixedly connected to the middle part of the support rod 141. The axis of the rotating shaft 142 coincides with the axis of the cylinder 11. The filter screen 115 is in the shape of a trumpet with a larger top and a smaller bottom. The outer periphery of the filter screen 115 is connected to the support ring 14, and the inner periphery of the filter screen 115 is connected to the rotating shaft 142. The alkali water production device for hydrogen production also includes a rotating device 15 for driving the support ring 14 to rotate around the axis of the rotating shaft 142, and the discharge port 116 is arranged above one side of the filter screen 115.

[0038] The above arrangement prevents the raw material from clumping on the filter 115, thereby increasing the speed of raw material dissolution. Specifically, the filter 115 is trumpet-shaped, resulting in a larger surface area. When the raw material settles on the filter 115, it is "spread" more widely, i.e., the thickness of the raw material is reduced, and the raw material dissolves more quickly. Furthermore, the discharge port 116 is located above one side of the filter 115. When the raw material is poured into the filter 115, it falls to one side of the filter 115 and begins to dissolve. Under the action of the rotating device 15, the filter 115 rotates about the axis of the rotating shaft 142, so that the raw material poured from the discharge port 116 falls to different positions on the filter 115, so that the raw material is uniformly received on the filter 115. This ensures that the raw material on the filter 115 is more evenly distributed, preventing the raw material from clumping on the filter 115. The support ring 14 and the rotating shaft 142 are used to support the filter 115. The rotating device 15 drives the filter 115 to rotate by driving the rotating shaft 142.

[0039] As an implementation method, the rotating device 15 includes a plurality of blades 151, which are arranged in a circular array with the axis of the rotating shaft 142 as the center. The water outlet 113 of the water inlet pipe 114 is close to the blades 151 and biased toward one side of the rotating shaft 142 to drive the blades 151 and the rotating shaft 142 to rotate.

[0040] Through the above arrangement, the pure water outputted from the water inlet pipe 114 impacts the blades 151 , thereby driving the rotation of the rotating shaft 142 .

[0041] As an implementation method, the water inlet pipe 114 and the cylinder 11 are slidably connected, and the alkali water production device for hydrogen production also includes a first driving device 16 for driving the water inlet pipe 114 to move along the axis of the water inlet pipe 114, and a second driving device 17 for driving the rotating shaft 142 to move along the axis of the rotating shaft 142.

[0042] The above arrangement facilitates the cleaning of the filter screen 115. Specifically, when the filter screen 115 needs to be cleaned, the water inlet pipe 114 moves toward the outside of the cylinder 11 under the action of the first driving device 16, thereby preventing the water inlet pipe 114 and the support ring 14 from interfering with each other. Then, under the action of the second driving device 17, the support ring 14 moves upward and moves to the upper side of the water inlet pipe 114. At this time, the filter screen 115 is located above the liquid level of the alkaline water. Then, under the action of the first driving device 16, the water inlet pipe 114 is close to the filter screen 115. Figure 4 At this time, the water inlet pipe 114 is close to the upper edge of the filter 115. After the pure water is input into the water inlet pipe 114, the pure water will impact the lower side of the filter 115, and part of the pure water will penetrate the filter 115 and reach the upper side of the filter 115. Figure 5 It should be noted that most of the impurities on the filter 115 are attached to the upper side of the filter 115. The pure water passing through the filter 115 will knock the impurities attached to the upper side of the filter 115 off the filter 115, and then as the pure water moves along the filter 115 toward the rotating shaft 142, the trumpet-shaped filter 115 plays the role of collecting impurities, that is, under the action of the pure water, the impurities are flushed out of the filter 115 and gathered in the concave part of the filter 115. In addition, the water outlet 113 of the water inlet pipe 114 is biased toward one side of the rotating shaft 142, so when the pure water output by the water inlet pipe 114 impacts the lower side of the filter 115, it will drive the filter 115 to rotate around the axis of the rotating shaft 142. During the rotation of the filter 115, the circumferential impurities of the filter 115 are all cleaned to the concave part of the filter 115, that is, the end of the filter 115 close to the rotating shaft 142. Finally, the personnel can use a spoon to clean up the impurities in the concave part of the filter 115 through the discharge port 116.

[0043] After the cleaning is completed, under the action of the first driving device 16, the water inlet pipe 114 moves away from the rotating shaft 142 again, thereby preventing the support ring 14 from interfering with the water inlet pipe 114 when moving downward. Then, under the action of the second driving device 17, the rotating shaft 142, the support ring 14, and the filter 115 move downward, and the support ring 14 moves back to the lower side of the water inlet pipe 114. Then, under the action of the first driving device 16, the water inlet pipe 114 moves closer to the rotating shaft 142. Figure 1 At this time, the filter 115 returns to the alkaline water and the alkaline water production can be restarted.

[0044] As an implementation method, a connecting plate 1141 is fixedly connected to the inner side of the water inlet pipe 114 near the end of the rotating shaft 142. The connecting plate 1141 is arranged on the lower side of the water inlet pipe 114. The connecting plate 1141 is rotatably connected to a water guide plate 1142. The water guide plate 1142 extends toward the blade 151 and in the horizontal direction. A return spring is arranged between the water guide plate 1142 and the connecting plate 1141. A first sliding groove 1143 is arranged on the lower side of the water inlet pipe 114. A slider 1144 is slidably connected in the first sliding groove 1143. The slider 1144 is connected to the inner side of the first sliding groove 1143. 44 abuts against the lower side of the water guide plate 1142, and the limiting protrusions 1145 are fixedly connected to the opposite sides of the upper end of the slider 1144, and the limiting protrusions 1145 abut against the inner wall of the water inlet pipe 114. A second slide groove 117 is provided on one side of the cylinder 11, and the water inlet pipe 114 passes through the second slide groove 117 and is slidably connected to the second slide groove 117. The lower end of the slider 1144 is provided with an inclined surface 1146 for driving the slider 1144 to move upward, and the inclined surface 1146 is at least partially provided on the outside of the first slide groove 1143.

[0045] By the above arrangement, the cleaning efficiency of the filter 115 can be further increased. Figure 1 At this time, the water guide plate 1142 extends horizontally, and the pure water output by the water inlet pipe 114 can directly impact the blades 151, thereby driving the rotation of the rotating shaft 142 very well. When the filter screen 115 needs to be cleaned, under the action of the first driving device 16, the water inlet pipe 114 moves away from the rotating shaft 142, and the inclined surface 1146 approaches the second chute 117. The lower side of the second chute 117 squeezes the inclined surface 1146 and causes the slider 1144 to move upward. The slider 1144 pushes the water guide plate 1142 to rotate upward. When the water guide plate 1142 rotates upward, the return spring twists, and the return spring applies torsion to the water guide plate 1142, so that the water guide plate 1142 is squeezed on the slider 1144. When the support ring 14 moves to the upper side of the water inlet pipe 114, the water inlet pipe 114 rotates and moves closer to the filter screen 115 under the action of the first driving device 16. Figure 5 At this time, the inclined surface 1146 and the second chute 117 are in contact with one end of the rotating shaft 142. At this time, the water guide plate 1142 is tilted. Specifically, the end of the water guide plate 1142 close to the filter 115 is tilted upward, so that when the pure water output by the water inlet pipe 114 is output, the pure water is tilted and impacts the filter 115 under the action of the water guide plate 1142. The direction of the pure water movement is more perpendicular to the filter 115 (not truly perpendicular, it can still drive the filter 115 to rotate), so that more pure water can penetrate the filter 115, making it easier for impurities attached to the filter 115 to be impacted. When the filter 115 is cleaned and the alkaline water production is restarted, see Figure 1At this time, under the action of the return spring, the water guide plate 1142 extends horizontally again, and the limiting protrusion 1145 prevents the slider 1144 from falling out of the first sliding groove 1143.

[0046] As an implementation method, a second connecting frame 133 is fixedly connected to the upper side of the first connecting frame 132, and the first driving device 16 includes a rack 161 fixedly connected to the water inlet pipe 114, a gear 162 fixedly connected to the rack 161, and a first motor 163 for driving the gear 162 to rotate, and the first motor 163 is arranged on the second connecting frame 133.

[0047] Through the above arrangement, the water inlet pipe 114 can be driven to move along the axis direction of the water inlet pipe 114 . When the first motor 163 drives the gear 162 to rotate, the gear 162 drives the water inlet pipe 114 to move along the axis direction of the water inlet pipe 114 through the rack 161 .

[0048] As an implementation method, the second driving device 17 includes a sliding seat 171 arranged on the upper side of the cylinder 11, a slide rail 172 fixedly connected to the upper side of the cylinder 11, a second motor 173 arranged at the upper end of the slide rail 172, and a screw rod 174 extending vertically connected to the second motor 173, the screw rod 174 passes through the sliding seat 171 and is threadedly connected to the sliding seat 171, the upper end of the rotating shaft 142 is inserted into the sliding seat 171 and is rotatably connected to the sliding seat 171, the upper end of the rotating shaft 142 is fixedly connected with an annular protrusion 1421, and a limiting groove 1711 adapted to the annular protrusion 1421 is provided in the sliding seat 171, and the annular protrusion 1421 is rotatably connected in the limiting groove 1711.

[0049] Through the above-mentioned arrangement, the rotating shaft 142 can be driven to move along the axis of the rotating shaft 142. Specifically, the second motor 173 drives the screw rod 174 to rotate, and the screw rod 174 and the sliding seat 171 rotate relative to each other, thereby driving the sliding seat 171 to move up and down. Under the action of the annular protrusion 1421, the sliding seat 171 will not move relative to the rotating shaft 142 in the up and down directions, so the sliding seat 171 will drive the rotating shaft 142 to move up and down, that is, the rotating shaft 142 moves along the axis direction of the rotating shaft 142.

[0050] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
