Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically relating to an additive dispensing device for a washing machine, particularly a switcher for a washing machine and the dispensing device, and also to a clothing processing device capable of washing and processing clothing. Background Technology

[0002] As consumers increasingly prioritize quality of life, washing machines have become indispensable. However, after a wash cycle, users often forget to remove clothes. If left unattended for too long, bacteria and unpleasant odors can grow inside the drum. Therefore, it's necessary to introduce fresh air into the drum to ventilate it. However, designing and controlling the fresh airflow path has become a pressing technical challenge.

[0003] Meanwhile, during the use of the washing machine, depending on the program being executed, the appropriate type of additive needs to be selected and added into the washing machine via different water channels and corresponding dispensing devices. In this process, the washing machine's additive dispensing device needs to have multiple switchable water channel combinations.

[0004] Therefore, how to design a switcher that can simultaneously control and switch the water path for additive delivery and the air path for fresh air flow has become an urgent technical problem to be solved.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a switcher to achieve the purpose of switching control of different media.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A switcher includes a device having two or more chambers, each chamber having at least one opening; a rotating rod passing through each chamber in sequence, the rotating rod having multiple cam portions that open opposite to different openings, each cam portion driving a piston that is correspondingly arranged to extend and retract relative to the opening, for controlling the sealing structure provided on different pistons to close or open the corresponding opening.

[0009] Furthermore, it includes a water-passing transfer chamber and an air-passing transfer chamber, which are independently set up, and each of the water-passing transfer chamber and the air-passing transfer chamber has at least one opening;

[0010] The same rotating rod passes through the underwater rotating cavity and the air-cooled rotating cavity in sequence. At the points where the rotating rod passes through the underwater rotating cavity and the air-cooled rotating cavity, there are cams that drive the pistons in the corresponding cavities to open and close.

[0011] Furthermore, the axis of the rotating rod extends in a straight line, and one end of the rotating rod is connected to a power unit installed outside the central cavity. The power unit is used to drive the rotating rod to rotate around the axis.

[0012] Furthermore, the axes of all openings in the water transfer chamber and the air transfer chamber are set along the radial direction of the rotating rod.

[0013] Furthermore, the rotating rod is provided with a first cam part that protrudes radially within the water-passing transfer chamber. The first cam part drives the pistons that are set one-to-one to move in and out relative to the opening, which is used to control the sealing structure set on different pistons to close or open the opening set on the water-passing transfer chamber.

[0014] And / or, the rotating rod is provided with a second cam portion that protrudes radially within the air transfer chamber. The second cam portion drives the pistons that are set one-to-one to move in and out relative to the opening, so as to control the sealing structure set on different pistons to close or open the opening set on the air transfer chamber.

[0015] Furthermore, the piston is provided with a through hole for the rotating rod to pass through. The rotating rod has a radially protruding rib that forms a cam part at the through hole. The distance between the protruding end of the rib and the axis of the rotating rod is greater than the radius of the through hole. The piston and the rotating rod together form a cam transmission structure. When the rotating rod rotates to the point where the rib abuts against the inner wall of the piston's through hole, it pushes the piston to move and drives the sealing structure to open the corresponding opening.

[0016] Preferably, the end of the piston near the opening is the sealing end, and the opposite end away from the opening is the supporting end. The sealing end of the piston is provided with a sealing ring that constitutes a sealing structure. The supporting end of the piston is connected to a spring that constitutes an elastic unit. The spring extends along the axis of the opening, and the two ends of the spring are respectively connected to the supporting end of the piston and the inner wall of the housing.

[0017] Furthermore, the present invention also provides a dispensing device that integrates the function of switching and controlling the types of additives dispensed, as well as the function of switching and controlling the airflow path. To achieve the above objectives, the present invention provides a dispensing device equipped with any of the aforementioned switchers. Different openings on at least one chamber of the switcher are respectively connected to different water passages of the dispensing device, for controlling the selective dispensing of different additives, either individually or in combination, into different water passages; and / or, different openings on at least one chamber are respectively connected to different air ducts of the dispensing device, for controlling the opening and closing of each air duct.

[0018] Meanwhile, the present invention also provides a clothing treatment device to blow fresh air into a water container, thereby reducing bacterial growth and odor. To achieve the above objectives, the present invention provides a clothing treatment device equipped with any of the aforementioned dispensing devices.

[0019] Furthermore, the dispensing device has two air transfer chambers, namely an air inlet transfer chamber and an air outlet transfer chamber;

[0020] An air outlet is provided at the bottom of the air inlet transfer chamber, which is connected to the air inlet of the water tank through the first air duct;

[0021] An air inlet is provided on the side wall of the air inlet transfer chamber. The air inlet is connected to the outside atmosphere through a fan installed outside the delivery device. The fan blows fresh air from the outside atmosphere into the air inlet transfer chamber.

[0022] An air inlet is located at the bottom of the air transfer chamber, which is connected to the air outlet of the water tank;

[0023] An air outlet is provided on the side wall of the air transfer chamber, which is connected to the outside of the clothing processing equipment through the second air duct.

[0024] Furthermore, the dispensing device has multiple storage chambers for storing different additives, and each pull-out storage chamber is connected to a different opening of the water transfer chamber via a different water path.

[0025] Furthermore, the dispensing device has multiple dispensing water channels, with the inlet end of each dispensing water channel corresponding to a different opening in the water transfer chamber, and the outlet end of each dispensing water channel connected to a water-holding cylinder.

[0026] Compared with the prior art, the present invention, by employing the above-described technical means, has the following significant technical advancements:

[0027] 1. This allows the same switch to control the on / off switching of different media flowing through different chambers, achieving the goal of simultaneously switching water and air paths with the same switch, thus enriching the application scenarios of the switch. Through the above settings, the switch can control both water and air paths simultaneously, increasing its application scenarios and enhancing its functional diversity.

[0028] 2. With the above settings, a fresh airflow can be directly formed from the outside of the water tank to the air outlet of the fan, passing through the transfer chamber and then being discharged to the atmosphere. This fresh airflow can refresh the gas inside the water tank, preventing bacterial growth in the washed clothes due to delayed drying. At the same time, the fan can be used to refresh the gas flow inside the water tank, achieving air blowing treatment of the clothes inside and improving the clothing treatment effect of the clothing treatment equipment.

[0029] Meanwhile, the present invention has a simple structure and significant effects, and is intended for widespread use.

[0030] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] A switcher 100 can be used to switch between different flow channels, water paths, and air paths, thereby achieving the effect of changing and regulating the flow direction of fluids. For example, the switcher 100 can be installed on the additive dispensing device of a washing machine to allow for the selective dispensing of different types of additives, either individually or in combination; and / or to dispense single or combined additives into the washing machine via different water paths and in different dispensing methods.

[0053] like Figures 1 to 9 As shown in the embodiment of the present invention, the switcher 100 has a housing 101, and the interior of the housing 101 is hollow to form a chamber 103. The housing 101 has a plurality of openings 102, each of which is connected to the chamber 103. A piston 104 is provided at each of some or all of the openings 102 to open and close the openings 102. Each piston 104 can be driven by a camshaft structure provided on the switcher 100 to generate relative displacement, thereby realizing the effect of controllable opening and closing of different openings 102 and combination switching of the connection forms of each opening 102 of the switcher 100.

[0054] In this embodiment of the invention, the camshaft structure is a rotating rod 108 that can rotate around an axis and is installed in the chamber 103 of the housing 101. The cam portion 109 provided on the rotating rod 108 drives the piston to move, thereby achieving the effect of opening and closing each opening.

[0055] In this invention, the opening and closing control of the opening 102 of the switch 100 is achieved by moving the piston 104. During the movement of the piston 104, the sealing structure 106 on the piston 104 (e.g., piston, sealing ring, etc.) will not come into contact with the inner wall of the housing 101 of the switch 100. This avoids the situation where the sealing structure 106, made of elastic materials such as rubber, is deformed and fails due to friction and compression with the inner wall of the housing 101 of the switch 100 during the opening and closing process. Example

[0056] like Figures 1 to 5 and Figures 6a to 6d As shown in the figure, this embodiment introduces a control valve structure. The control valve structure can be a control device for controlling the opening and closing of any opening 102 on the switch 100; of course, it can also be used alone and applied to other devices.

[0057] In this embodiment, the control valve structure includes: a housing 101, a hollow chamber 103 formed inside the housing 101, an opening 102 communicating with the chamber 103 on the housing 101, and a piston 104 that can extend and retract relative to the opening installed in the chamber 103; a drive structure for driving the piston 104 to move is installed on the housing 101, which is used to control the sealing structure 106 on the piston 104 to close or open the opening 102 accordingly.

[0058] like Figures 1 to 5 and Figures 6a to 6d As shown, in this embodiment, the driving structure includes,

[0059] The rotating rod 108, driven by the power unit, is installed in the chamber 103 and can rotate around an axis;

[0060] The rotating rod 108 is provided with a radially protruding cam portion 109. The cam portion 109 and the piston 104 at least partially overlap in the axial direction of the rotating rod 108. The distance between the protruding end of the cam portion 109 and the axis of the rotating rod 108 is greater than half the distance between the piston 104 and the axis of the rotating rod 108, so that the piston 104 can be driven to extend and retract during the rotation of the rotating rod 108 by the cam portion 109.

[0061] like Figures 6a to 6d As shown, in this embodiment, the piston 104 is provided with a through hole for the rotating rod 108 to pass through, and the rotating rod 108 is provided with a radially protruding rib at the through hole. The rib forms a cam portion 109. The piston 104 and the rotating rod 108 together form a cam transmission structure. When the rotating rod 108 rotates to the point where the rib abuts against the inner wall of the through hole of the piston 104, it pushes the piston 104 to move and drives the sealing structure 106 to open the corresponding opening.

[0062] In this embodiment, the driving structure further includes an elastic unit 105, which is clamped between the piston 104 and the housing 101. This unit provides an elastic restoring force to the piston 104 to close the corresponding opening of the sealing structure 106. When the rotating rod 108 rotates until the rib separates from the inner wall of the through hole of the piston 104, the elastic unit 105 pushes the piston 104 to move, causing the sealing structure 106 to block the opening 102. In this embodiment, the elastic unit 105 can be a spring, a pneumatic cylinder, a hydraulic cylinder, etc., any existing device or combination that provides an elastic restoring force. Preferably, in this embodiment, the elastic unit 105 is a spring.

[0063] like Figures 1 to 5 and Figures 6a to 6d As shown, in this embodiment, the piston 104 is a block structure extending axially along the opening 102. The piston 104 of the block structure has a through hole in the middle that passes through both sides. The axis of the rotating rod 108 is parallel to the axis of the through hole and passes through the through hole. The part of the rotating rod 108 that passes through the through hole has radially outward protruding ribs. The ribs constitute a cam part 109 that pushes the piston 104 to move telescopically.

[0064] In this embodiment, the axial direction of the through hole provided on the piston 104 is perpendicular to the axial direction of the opening 102, so that the driving force of the rotation direction of the rotating rod 108 is transmitted to the piston 104 through the cam structure, so that the piston 104 can generate a pushing displacement along the radial direction of the rotating rod 108, thereby realizing the effect of the piston 104 moving axially and extending along the opening 102, and using the sealing structure on the piston 104 to correspond to the opening and closing of the opening 102.

[0065] In this embodiment, the end of the piston 104 near the opening 102 is the sealing end, and the opposite end away from the opening 102 is the supporting end. The sealing end of the piston 104 is provided with a sealing structure 106. The sealing structure 106 is a sealing ring 125 made of elastic material such as rubber. The sealing ring 125 is coaxially arranged with the opening 102 and can make sealing contact with the inner wall of the chamber 103 on the outer periphery of the opening 102, thereby achieving the effect of sealing and closing the opening 102. In this embodiment, the sealing end of the piston 104 is provided with a columnar piston head protruding outward along the axis of the opening. The sealing ring 125 is sleeved on the outer periphery of the piston head 126 and is clamped and fixed on the piston head 126 by the action of a radially protruding ring of ribs on the piston head 126.

[0066] In this embodiment, the support end of the piston 104 is connected to a spring constituting the elastic unit 105. The spring extends along the axial direction of the opening 102, and the two ends of the spring are respectively connected to the support end of the piston 104 and the inner wall of the housing 101.

[0067] Preferably, in this embodiment, the sealing structure 106 and the elastic unit 105 are coaxially arranged with the piston 104 to ensure that the piston does not deviate during movement and to improve the sealing effect. More preferably, the sealing structure 106, the elastic unit 105, and the piston 104 are all coaxially arranged with the opening 102.

[0068] In this embodiment, the inner peripheral wall of the through hole in the middle of the piston 104 is provided with a protrusion 127 that protrudes radially toward the center of the through hole. The protrusion 127 is located on the side of the through hole near the support end. The protrusion 127 enables the cam portion 109 of the rotating rod 108 to effectively push the piston 104 to move and increase the extension and retraction distance of the piston 104, thereby effectively realizing the control of the sealing structure 106 on the piston 104 to effectively close and open the opening 102.

[0069] Preferred, such as Figures 6a to 6d As shown, in this embodiment, the protrusion 127 is a triangular protrusion that slopes from the left and right sides toward the center, so that the inclined surfaces on both sides can effectively guide the cam 109 and prevent imbalance during the piston 104's operation.

[0070] like Figures 6a to 6d As shown, in this embodiment, a limiting post 123 protruding axially along the opening 102 is provided on the side of the inner wall of the housing 101 facing the supporting end of the piston 104. One end of the spring clamped between the supporting end of the piston 104 and the inner wall of the housing 101 is connected to the limiting post 123. In this embodiment, the supporting end of the piston 104 is provided with a mounting groove 124 opening towards the limiting post 123. One end of the spring constituting the elastic unit 105 is inserted into the mounting groove 124, and the other end is fitted onto the outer peripheral wall of the limiting post 123.

[0071] like Figures 1 to 5 and Figures 6a to 6d As shown, in this embodiment, the chamber 103 is provided with a guide part 107 to guide the piston 104 to move telescopically along the axial direction of the opening 102, so as to ensure that the piston 104 will not tilt in other directions during the telescopic movement and can only move along the axial direction of the opening 102, thereby effectively avoiding the occurrence of piston 104 position deviation and inability to be driven and controlled by the rotating rod 108.

[0072] In this embodiment, the inner wall of the housing 101 is provided with a piston groove that extends along the axial direction of the opening 102 and forms a guide portion 107. The side wall of the piston 104 is inserted into the piston groove. The side wall of the piston 104 inserted into the piston groove is the other side of the non-piston sealing end and the support end. Preferably, the side wall of the piston 104 is the side that is parallel to the axial direction of the rotating rod 108.

[0073] In this embodiment, the left and right side walls of the piston 104 are respectively inserted into the piston grooves in the inner wall of the corresponding side housing 101. The piston grooves on both sides are arranged in parallel and extend in a direction parallel to the axis of the opening 102. Preferably, the piston grooves on both sides are in the same cross section as the axis of the opening 102, so as to ensure that the piston 104 is always in the axial cross section of the opening 102, thereby effectively avoiding the occurrence of piston 104 displacement. Example

[0074] like Figures 1 to 9 As shown, this embodiment introduces a switcher 100, which includes: a housing 101, the housing 101 being hollow to form a chamber 103, the housing 101 having multiple openings 102 communicating with the chamber 103, a rotating rod 108 rotatable about an axis installed in the chamber 103, the rotating rod 108 having multiple cam portions 109 opening opposite to different openings 102, each cam portion 109 driving a piston 104 corresponding to it to extend and retract relative to the opening 102, for controlling the sealing structure 106 on different pistons 104 to close or open the corresponding opening 102.

[0075] In this embodiment, the valve body structure provided at each opening 102 of the switch 100 to control the opening and closing of the opening 102 is the control valve structure described in the above embodiment, so as to achieve the effect of effectively controlling the opening and closing of multiple openings 102 by using a single rotating rod 108.

[0076] like Figures 1 to 3 As shown, in this embodiment, the cam portions 109 provided on the rotating rod 108 are arranged alternately along the axial direction of the rotating rod 108, and each cam portion 109 is located at the cross section of a different opening 102, so as to effectively control the opening and closing of the corresponding opening 102.

[0077] Preferably, in this embodiment, the radial protrusion positions of different cam portions 109 relative to the axis of the rotating rod 108 are the same or different, so that when the rotating rod 108 rotates around the axis to the corresponding position, the cam portions 109 drive the pistons 104 at different openings 102 to open and move separately or simultaneously.

[0078] In this embodiment, the housing 101 of the switcher 100 is provided with a plurality of openings 102 on one side, and each opening 102 is arranged at intervals along a straight line. The axis of the rotating rod 108 provided in the chamber 103 is parallel to the aforementioned straight line. The rotating rod 108 is provided with a cam portion 109 that corresponds one-to-one with some or all of the aforementioned openings 102. The cam portion 109 and the corresponding opening 102 are in the same cross section.

[0079] In this embodiment, pistons 104 are provided at different openings 102 of the housing 101 of the switcher 100. Each piston 104 is provided with a sealing structure 106 that blocks the corresponding opening 102. Each piston 104 is provided with a through hole. The rotating rod 108 passes through each through hole in sequence. The part of the rotating rod 108 that passes through each through hole is provided with a cam part 109 for driving the corresponding piston 104 to move.

[0080] In this embodiment, the inner wall of the through hole of the piston 104 is provided with a protrusion 127 that protrudes toward the center of the through hole and abuts against the cam portion 109. The protrusion 127 is located on the side of the inner wall of the through hole away from the opening 102. Preferably, in this embodiment, a spring unit 105 is provided between the piston 104 and the inner wall of the housing 101. The spring applies a pushing force to the piston 104 toward the opening 102, which is used to push the sealing structure 106, such as the sealing ring provided on the piston 104, to close the opening 102.

[0081] This embodiment can also be configured as follows: multiple openings 102 are provided on different side walls of the housing 101 of the switcher 100; when each opening 102 is located at a different cross section of the housing 101, the moving direction of the piston 104 of the openings 101 on different side walls needs to be differentiated, but it must be ensured that the axis of each opening 102 on each side wall of the housing 101 of the switcher 100 is perpendicular to the axis of the rotating rod 108; of course, to ensure the opening and closing effect, a perpendicular setting is preferred, but if only for opening and closing control, it is sufficient to set the axis of the opening 102 to intersect the axis of the rotating rod 108. With the above configuration, a single rotating rod 108 can be used to control the opening and closing of multiple openings 102 on different side walls, realizing the combined switching of the connection status of each opening 102 (not shown in the figures).

[0082] In this embodiment, the switcher can also be configured as follows: the chamber 103 of the housing 101 is provided with two or more rotating rods 108, and each rotating rod 108 is provided with a cam portion 109 for controlling the relative extension and retraction of different or the same pistons 104, so as to achieve the purpose that different rotating rods 108 can control the same opening 102, or different rotating rods 108 can control different openings 102 separately, thereby further increasing the number of opening and closing combinations of each opening 102 of the switcher 100 (not shown in the figures).

[0083] In this embodiment, the switcher can also be configured as follows: Figures 1 to 9As shown, the housing 101 is provided with multiple chambers 103, and each chamber 103 is provided with at least one rotating rod 108. Each chamber 103 has at least one opening 102. The rotating rod 108 in each chamber 103 pushes the corresponding piston 104 to move and extend via the cam part 109, thereby controlling the opening and closing of each opening 102 in the chamber 103. This enables the switch 100 to control two or more sets of passages separately.

[0084] like Figures 1 to 9 As shown, in this embodiment, a motor 110 is provided on the housing 101. The output end of the motor 110 is directly or via a transmission structure connected to the rotating rod 108 to drive the rotating rod 108 to rotate around the axis and control the rotation angle of the rotating rod 108, so as to achieve precise control of the rotation position of the rotating rod 108. Then, when the rotating rod 108 rotates to different rotation positions, the cam part 109 pushes different pistons 104 to move, thereby achieving the effect of controlling the opening and closing of different openings 102 on the switcher 100 respectively.

[0085] Preferably, in this embodiment, the end of the rotating rod 108 extends out of the housing 101, and the end extends out and is connected to the output end of the motor 110 installed on the outside of the housing via the reduction gear set 121, so as to achieve precise control of the rotation position of the rotating rod 108 and thus achieve a significant technical advancement in improving the control accuracy of the switch 100. Example

[0086] like Figures 1 to 9 As shown, this embodiment introduces a switch 100, which includes a housing 101 with a hollow chamber 103 inside; the housing 101 has a mounting hole 120 for a rotating rod 108 to pass through, and the part of the rotating rod 108 passing through the mounting hole 120 is fitted with two sealing rings in sequence; there is a pressure relief chamber 115 between the outer wall of the rotating rod 108 and the inner wall of the mounting hole 120 between the two sealing rings, and the housing 101 has a pressure relief port 117 that connects the pressure relief chamber 115 to the outside of the chamber 103.

[0087] With the above settings, after the sealing ring of the switch 100 fails, the water leaking from the point where the rotating rod 108 protrudes can be diverted to other locations through the pressure relief chamber 115, effectively preventing water leakage directly from the point where the rotating rod 108 protrudes. At the same time, by connecting the pressure relief chamber to the outside of the chamber through the pressure relief port, the pressure in the chamber at the point where the rotating rod protrudes is significantly reduced, thereby effectively preventing water leakage from the point where the rotating rod protrudes.

[0088] like Figures 7 to 9As shown, in this embodiment, the outer wall of the rotating rod 108 is provided with a groove 116, the groove 116 is open and faces the inner wall of the mounting hole 120, the groove 116 is located between two sealing rings, and the groove 116 and the inner wall of the mounting hole 120 form a pressure relief cavity 115; the groove 116 is arranged around the outer periphery of the rotating rod 108, and the groove 116 can be continuously or discontinuously extended for at least one turn.

[0089] In this embodiment, a groove 116 may be provided on the inner wall of the mounting hole 120. The opening of the groove 116 faces the outer wall of the rotating rod 108. The groove 116 is located between two sealing rings, and the groove 116 and the outer wall of the rotating rod 108 form a pressure relief cavity 115. The groove 116 is arranged around the inner circumference of the mounting hole 120, and the groove 116 may be continuously or discontinuously extended for at least one circle, which can also achieve the above-mentioned invention objective.

[0090] In this embodiment, a sealing ring is fitted around the outer periphery of each end of the portion of the rotating rod 108 that passes through the mounting hole 120. The inner and outer periphery of the sealing ring are respectively sealed and fitted to the outer wall of the rotating rod 108 and the inner wall of the mounting hole 120. The inner sealing ring 113 is provided at the end near the chamber 103, and the outer sealing ring 114 is provided at the end away from the chamber 103. The pressure relief chamber 115 is located between the inner and outer sealing rings 113 and 114, and is connected to the space between the inner and outer sealing rings 113 and 114.

[0091] In this embodiment, the inner wall of the mounting hole 120 is provided with a radially outwardly recessed notch. The notch is in the same cross section as the inner sealing ring 113 and is used to connect the two sides of the inner sealing ring 113. Preferably, multiple notches are arranged circumferentially on the inner wall of the mounting hole 120. By providing a notch on the inner circumferential side wall of the mounting hole 120 to connect the two sides of the inner sealing ring 113, some water in the chamber 103 can flow into the pressure relief chamber 115 through the notch, thereby reducing the water pressure near the point where the rotating rod 108 passes through the chamber and effectively reducing the occurrence of leakage faults in the switch 100.

[0092] like Figures 7 to 9 As shown, in this embodiment, the housing 101 of the switcher 100 is provided with an independent high-pressure chamber 111 and a low-pressure chamber 112. A rotating rod 108 is provided inside the high-pressure chamber 111.

The pressure relief port 117 of the pressure relief chamber 115 is connected to the low-pressure chamber 112 via a pressure relief channel 118. Through this arrangement, all water flowing out of the pressure relief chamber 115 can flow into the low-pressure chamber 112, achieving effective collection of the pressure-relieved water. Simultaneously, it effectively reduces the water pressure at the point where the rotating rod 108 exits the high-pressure chamber 111, effectively preventing water leakage from the point where the rotating rod 108 exits.

[0093] In this embodiment, a second rotating rod is provided inside the low-pressure chamber 112, with the end of the second rotating rod extending out of the low-pressure chamber 112. A sealing ring is provided on the outer peripheral wall of the part of the second rotating rod 112 that extends out. The low-pressure chamber 112 is provided with a communication port 119 that communicates with the pressure relief channel 118. The communication port 119 is positioned close to the center of the low-pressure chamber 112 relative to the sealing ring, so that the liquid flowing out of the high-pressure chamber through the pressure relief channel can flow into the low-pressure chamber, thereby achieving the effect of effectively collecting the pressure relief water flow.

[0094] In this embodiment, the low-pressure chamber 112 is connected to the outside atmosphere through a pressure relief port equipped with a pressure relief valve 122, so as to reduce the air pressure in the low-pressure chamber as much as possible and make it consistent with the outside atmosphere; preferably, the pressure relief port is located close to the connection port 119.
