Description

Technical Field

[0001] The present application relates to the technical field of washing equipment, and in particular to a clothing processing equipment. Background Art

[0002] Washing machines and other clothing processing equipment are cleaning appliances that use electrical energy to create mechanical action to wash clothes.

[0003] The clothing processing device generally includes a housing, an inner drum, an outer drum, a door body and a door seal. The housing has a clothing access opening, the outer drum is arranged in the housing, the inner drum is arranged in the outer drum, and the drum mouth of the outer drum faces the clothing access opening. The door body is connected to the housing to cover the clothing access opening. The door seal is arranged between the outer drum and the door body. Among them, clothing can be put into the inner drum through the clothing access opening so that the clothing can be washed by the clothing processing device.

[0004] However, when the clothes processing device is not heated for washing, the washing time is long and the washing effect is poor. Utility Model Content

[0005] The purpose of this application is to at least solve the above-mentioned problems.

[0006] The purpose of the present application is also to instantly increase the flow rate and pressure of the liquid when the liquid is sprayed through the spray hole, so that the clothes can be washed efficiently, ensuring that the clothes processing equipment has a better washing effect.

[0007] The purpose of the present application is not limited to the above-mentioned purpose, and those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0008] The laundry processing apparatus of the present application for achieving the above-mentioned object includes a housing.

[0009] The clothes processing device comprises an outer drum which is arranged in a shell and has a cavity in the outer drum.

[0010] The clothes processing device comprises an inner drum which is rotatably arranged in an outer drum and has a clothes washing cavity which is communicated with the cavity body.

[0011] The clothes processing device comprises a liquid inlet pipeline, which comprises a water inlet pipeline or a circulation pipeline connected to the cavity of the outer drum.

[0012] The clothing treatment device includes a spray assembly. The spray assembly includes a spray head, which is connected to the water outlet of the liquid inlet pipeline. The liquid in the liquid inlet pipeline is sprayed to the inner drum through the spray head. The spray head is provided with a spray hole for washing water.

[0013] In the laundry treatment device, along the flow direction of the liquid in the spray hole:

[0014] The spray hole has a liquid inlet section and a liquid outlet section, the liquid inlet section presents a contraction structure, and the liquid outlet section presents an expansion structure.

[0015] The present application provides a clothing treatment device, which is provided with a contraction structure in the liquid inlet section and an expansion structure in the liquid outlet section along the flow direction of the liquid in the spray hole, so that along the flow direction of the liquid in the spray hole, the cross-sectional area of ​​the liquid inlet section gradually decreases, and the cross-sectional area of ​​the liquid outlet section gradually increases. In this way, when the liquid flows in the liquid inlet section, the flow velocity of the liquid in the process of flowing in the liquid inlet section continues to increase, and after increasing to a critical point, the flow velocity of the liquid will no longer increase. When the liquid enters the liquid outlet section, the liquid continues to accelerate and becomes supersonic, so that the flow velocity of the liquid can be instantly increased when the liquid is sprayed out through the spray hole. When the flow velocity of the liquid increases instantly, the pressure of the liquid also increases instantly, which can effectively wash the clothes in the inner drum and improve the washing effect. In addition, since the cross-sectional area of ​​the liquid outlet section gradually increases along the flow direction of the liquid in the spray hole, the liquid has a larger spraying area when it is sprayed to the inner drum through the liquid outlet section, so that the liquid sprayed to the inner drum through the spray hole can cover and rinse the clothes in the inner drum over a large area, which can efficiently wash the clothes and improve the washing effect. In addition, the liquid sprayed into the inner drum by the sprinkler head can not only rinse the inner drum over a larger area, but also the door seal, door body, etc., to avoid impurities such as foam generated by detergent from remaining in the inner drum, door seal, and door body, thereby improving the cleaning effect and ensuring the health of clothing users.

[0016] In some embodiments, along the flow direction of the liquid in the spray hole:

[0017] The inner diameter of the liquid inlet section gradually decreases, and the inner diameter of the liquid outlet section gradually increases, and the inner diameters of the liquid inlet section and the liquid outlet section at the opposite ends are equal, so that along the flow direction of the liquid in the spray hole, the cross-sectional area of ​​the liquid inlet section gradually decreases, forming a contraction structure, and the cross-sectional area of ​​the liquid outlet section gradually increases, forming an expansion structure. In addition, since the inner diameters of the liquid inlet section and the liquid outlet section at the opposite ends are equal, a narrow channel is formed between the liquid inlet section and the liquid outlet section of the spray hole. When the liquid flows from the liquid inlet section to the narrow channel, the flow rate of the liquid is at the critical point mentioned above.

[0018] In some embodiments, the liquid inlet section is directly connected to the liquid outlet section, or,

[0019] The spray hole has a connecting section, where the liquid inlet section and the liquid outlet section are connected. Along the flow direction of the liquid in the spray hole, the inner diameters of the connecting section are equal, and the inner diameter of the connecting section is equal to the minimum inner diameter of the liquid inlet section and the liquid outlet section.

[0020] By directly connecting the liquid inlet section with the liquid outlet section, or by setting a connecting section, the structure of the spray hole can be made more diversified to meet the design requirements of different spray heads for the spray hole. Compared with the setting of the connecting section, when the liquid inlet section is directly connected to the liquid outlet section, the liquid pressure is instantly increased, the spraying area is increased, and it is also conducive to miniaturization of the spray head.

[0021] In some embodiments, the spray head has a plurality of spray holes. The plurality of spray holes are arranged on the side of the spray head facing the inner cylinder, so that the liquid in the liquid inlet pipeline is sprayed into the inner cylinder through the spray holes. At the same time, the arrangement of the plurality of spray holes can further expand the spray area, so as to obtain a just cleaning effect and a flushing effect on the inner cylinder, the door seal, the door body, etc.

[0022] In some embodiments, the spray head has a plurality of hole groups on one side facing the inner barrel. The plurality of hole groups include a first hole group and a second hole group, and both the first hole group and the second hole group have spray holes. The number of spray holes in the second hole group is greater than the number of spray holes in the first hole group, and the size of the spray holes in the second hole group is smaller than the size of the spray holes in the first hole group.

[0023] By limiting the size and number of the spray holes in the second hole group and the first hole group, two different water flow effects can be generated when the liquid in the liquid inlet pipeline is sprayed into the inner drum through the first hole group or the second hole group, so that the spray head can generate a water flow effect adapted to the type of clothing to wash, rinse, etc. the clothing.

[0024] In some embodiments, the spray assembly further includes an insert, and the spray head has an insert hole.

[0025] The insert is embedded in the embedding hole, and the circumferential outer wall of the insert and the hole wall of the embedding hole together form a spray hole.

[0026] The plurality of hole groups further include a third hole group having at least one injection hole.

[0027] By setting the injection holes, the liquid in the liquid inlet pipeline can be injected into the inner cylinder from a circle around the insert, forming a closed waterfall-like water flow effect around the insert. On the basis of the first hole group and the second hole group, the diversity of the water flow effect can be further enhanced.

[0028] In some embodiments, the spray assembly further includes a spray pipe and a fixing member, wherein the spray pipe is connected to the water outlet end of the liquid inlet pipeline and is connected to the fixing member.

[0029] The fixing part has a connecting hole. The spray head is installed on the fixing part, and the spray head is connected with the spray pipe through the connecting hole;

[0030] The spray head rotates relative to the fixed part so that the spray pipe is connected to one of the multiple hole groups, so that the user can rotate the spray head according to the water flow requirements of the clothes and select one of the hole groups to be connected to the spray pipe, so that when the clothing processing equipment is in the washing, rinsing and other programs, the water flow effect suitable for the washed clothes can be generated through the selected hole group.

[0031] In some embodiments, a side of the fixing member facing the shower head has a deformable protrusion, and the protrusion is located at an edge area of ​​the fixing member.

[0032] The shower head has a positioning part for clamping the protrusion on one side facing the fixing part, and the positioning part is located at the edge area of ​​the shower head. The shower head has a positioning part at the position corresponding to each hole group, and the positioning parts are evenly distributed along the circumference of the shower head.

[0033] When the shower head rotates relative to the fixing member until the protrusion is clamped in one of the positioning parts, the shower pipe is connected to one of the hole groups, and the hole group connected to the shower pipe corresponds to the positioning part of the clamping protrusion.

[0034] By rotating the spray head, the protrusions can be snapped onto the positioning parts in sequence, and each hole group can be positioned, so that during the rotation, each hole group can be connected to the spray pipe in sequence to obtain a variety of different water flow effects.

[0035] In some embodiments, the spray assembly further includes a sealing member. The sealing member is disposed at the periphery of the connecting hole to seal the fixing member and one of the hole groups to prevent the liquid flowing through the connecting hole from entering the unselected hole group and affecting the water flow effect of the spray head; and / or,

[0036] The fixing piece is provided with a cantilever, and the free end of the cantilever faces the edge area of ​​the fixing piece. A convex portion is provided on the side of the free end facing the shower head, so that the convex portion is arranged at the edge area of ​​the fixing piece, and at the same time, it can also ensure that the convex portion can be deformed.

[0037] In some embodiments, the shower head has a plurality of protrusions on one side away from the fixing member. The number of protrusions corresponds to the number of hole groups and one-to-one corresponds to each other. Each protrusion is provided with a hole group so that each hole group can be provided on a corresponding protrusion. Moreover, when the user rotates the shower head, the protrusions can be acted on so that the user can rotate the shower head. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0066] The embodiment of the present application provides a clothes processing device, which may include a washing machine, a shoe washer, or other washing device capable of washing clothes and objects. For example, the washing machine may be a drum washing machine or a pulsator washing machine.

[0067] Figure 1 A structural diagram of a clothes processing device 10 is schematically shown. Figure 1 The laundry processing device 10 is a drum washing machine. Figure 1 Taking a drum washing machine as an example, the structure of the clothes processing device 10 is further described.

[0068] See also Figure 1 As shown, the laundry processing device 10 may include a housing 20. The housing 20 has a laundry taking-in and putting-out opening.

[0069] The laundry processing apparatus 10 may include an outer drum 40. The outer drum 40 is disposed in the housing 20, and the drum opening of the outer drum 40 faces the laundry taking-in and putting-out opening.

[0070] The clothing processing device 10 may include an inner drum 50. The inner drum 50 is rotatably disposed in the outer drum 40, and the tube mouth of the outer drum 40 is also facing the clothing loading and unloading port. The inner drum 50 has a clothing washing cavity. During the process of washing clothes, the inner drum 50 can rotate relative to the outer drum 40 to wash the clothes in the clothing washing cavity. The clothing washing cavity is connected to the cavity of the outer drum 40. For example, a plurality of through holes can be opened on the inner drum 50, and the plurality of through holes can be evenly distributed on the wall of the inner drum 50. The water in the clothing washing cavity can flow into the outer drum 40 through the through holes on the wall of the inner drum 50, and can be discharged from the outer drum 40 after the washing is completed.

[0071] See also Figure 1 As shown, the laundry processing device 10 may further include a door body 30. The door body 30 is connected to the housing 20 to cover the laundry access opening. For example, the door body 30 may be provided at the laundry access opening and rotatably connected to the housing 20 so that the door body 30 can cover the laundry access opening, and at the same time, the door body 30 can be easily opened so that the laundry can be put into the inner drum 50 through the laundry access opening, and the laundry can be washed by the laundry processing device 10.

[0072] See also Figure 1As shown, the clothes treating apparatus 10 may further include a door seal 60. The door seal 60 is disposed between the tube opening of the outer drum 40 and the door body 30 to seal the gap between the door body 30 and the tube opening of the outer drum 40. The door body 30 may be a glass door body so that the user can observe the condition of the clothes in the inner drum 50 through the door body 30.

[0073] The laundry processing device 10 may further include a water inlet pipeline (not shown). A portion of the water inlet pipeline is disposed inside the housing 20, and another portion is disposed outside the housing 20, so that the water inlet pipeline is connected to an external water source (such as a faucet). Water is injected into the inner drum 50 through the water inlet pipeline, and at the same time, the water flowing through the water inlet pipeline can bring detergent into the inner drum 50, so that the laundry processing device 10 can wash the clothes with the cooperation of water and detergent.

[0074] See also Figure 1 As shown, the laundry treatment apparatus 10 may further include a drain pipe 80. A portion of the drain pipe 80 is disposed inside the housing 20, and another portion is disposed outside the housing 20, so as to drain liquid to the outside of the housing 20.

[0075] The clothes treating apparatus 10 may further include a drain pump 70. The drain pump 70 is disposed in the housing 20 and may be connected to the outer tub 40 so that the liquid in the outer tub 40 can enter the outer tub 40, and the drain pump 70 can pump the liquid in the outer tub 40 into the drain pipe 80. The water inlet end of the drain pump 70 may be connected to the drain port of the outer tub 40 to achieve the connection between the drain pump 70 and the outer tub 40.

[0076] The laundry processing device 10 has a laundry processing program. The laundry processing program includes a washing program, a rinsing level, etc. When the laundry processing program is a washing program, the liquid formed by the mixture of water and detergent in the inner drum 50 and the outer drum 40 can be referred to as washing water. When the laundry processing program is a rinsing level, the liquid in the inner drum 50 and the outer drum 40 can refer to the water in the inner drum 50 and the outer drum 40, or a mixed liquid formed by the mixture of water and a whitening agent, etc.

[0077] The laundry processing device 10 may further include a heater. The heater can heat the liquid in the inner drum 50, so as to realize the function of the laundry processing device 10 to heat and wash the laundry, thereby improving the laundry cleaning effect of the laundry processing device 10 on the laundry.

[0078] However, the existing clothes treatment equipment takes a long time to wash without heating, and the washing effect is poor. Moreover, after the washing is completed, detergent foam and other impurities may remain in the door and other places. Over time, these residual impurities will become moldy and smelly, resulting in poor washing effect of clothes, which affects the health of users.

[0079] To this end, the laundry processing device may further include a circulation pipeline 90. The circulation pipeline 90 and the water inlet pipeline may be used as two different liquid inlet pipelines. That is, the liquid inlet pipeline includes the water inlet pipeline and the circulation pipeline 90. At least part of the liquid inlet pipeline is arranged in the housing 20. For example, when the liquid inlet pipeline is the circulation pipeline 90, the circulation pipeline 90 may be partially arranged in the housing 20, or may be entirely arranged in the housing 20. The arrangement of the water inlet pipeline in the housing 20 may refer to the relevant description above.

[0080] The circulation pipeline 90 may be in communication with the cavity in the outer cylinder 40 , so that the liquid in the inner cylinder 50 and the outer cylinder 40 may enter the circulation pipeline 90 .

[0081] The clothing treatment device 10 may further include a spray head 120. The spray head 120 has a spray hole 121. The spray head 120 is connected to the circulation pipeline 90, and the circulation pipeline 90 can introduce the liquid discharged from the inner drum 50 and the outer drum 40 into the spray head 120. The liquid in the inner drum 50 and the outer drum 40 can be sprayed into the inner drum 50 through the spray hole 121, and the liquid is sprayed onto the clothes, so that the clothes can be effectively rinsed, thereby effectively soaking the clothes, realizing the internal circulation spray function of the clothing treatment device 10, improving the washing effect, and then improving the cleaning effect, and at the same time, it has the characteristics of saving time and water.

[0082] However, in the related art, the spray holes on the spray head are usually circular holes, so that after the liquid in the inner drum 50 and the outer drum 40 is sprayed into the inner drum 50 through the spray holes, the coverage area and pressure in the inner drum 50 are limited, making it difficult to wash clothes efficiently, and the washing effect of the clothing processing equipment needs to be improved.

[0083] In view of this, see Figure 1 As shown, the clothing treatment device 10 of the embodiment of the present application may be provided with a liquid inlet pipeline and a spray assembly 100. The spray assembly 100 may have a spray head 120 connected to the water outlet end of the liquid inlet pipeline, and a spray hole 121 is provided on the spray head 120. The present application improves the shape of the spray hole 121 of the spray head 120 so that the pressure of the liquid can be instantly increased when the liquid is sprayed through the spray hole 121, and has a larger spray area, so that the liquid sprayed by the spray head 120 to the inner drum 50 can cover and rinse the clothes in the inner drum 50 over a large area, and can wash the clothes efficiently and improve the washing effect. At the same time, the liquid sprayed by the spray head 120 to the inner drum 50 can also rinse the inner drum 50, the door seal 60, the door body 30, etc., to avoid the impurities such as foam generated by the detergent remaining in the inner drum 50 and the door body 30, so as to ensure the washing effect of the clothes and the health of the user.

[0084] The spraying region of the spraying assembly 100 may include the spraying region of the spraying hole 121. Accordingly, the spraying area of ​​the spraying assembly 100 may include the area occupied by the spraying region of the spraying hole 121.

[0085] The structure of the clothes processing device 10 is further described below in conjunction with the accompanying drawings and embodiments.

[0086] Figures 2 to 4 The schematic diagram shows the structure of the first spray assembly at different viewing angles. Figure 5 yes Figure 4 A schematic structural diagram of the middle shower head 120 at a first viewing angle.

[0087] See also Figures 1 to 4 As shown, the laundry treatment apparatus 10 may include a liquid inlet pipeline. The liquid inlet pipeline may include a circulation pipeline 90, a water inlet pipeline or other liquid inlet channels in the laundry treatment apparatus 10.

[0088] See also Figures 2 to 5 As shown, the clothing treatment device 10 may further include a spray assembly 100. The spray assembly 100 may include a spray head 120. The spray head 120 may be connected to the water outlet end of the liquid inlet pipeline. The liquid in the liquid inlet pipeline is sprayed to the inner drum 50 through the spray head 120, so that the liquid in the liquid inlet pipeline can be sprayed into the inner drum 50 through the spray head 120, thereby washing the clothes in the inner drum 50.

[0089] Figure 6 Shows Figure 2 The cross-section view in the AA direction, Figure 7 Shows Figure 3 Cross-sectional view in the BB direction.

[0090] See also Figure 6 and Figure 7 As shown, the spray head 120 may have a spray hole 121 for spraying liquid, so that the liquid in the liquid inlet pipeline can be sprayed into the inner drum 50 through the spray hole 121, thereby washing the clothes in the inner drum 50.

[0091] See also Figure 7 As shown, along the flow direction of the liquid in the spray hole 121:

[0092] The spray hole 121 may have a liquid inlet section 1211 and a liquid outlet section 1212 , wherein the liquid inlet section 1211 may have a contraction structure, and the liquid outlet section 1212 may have an expansion structure.

[0093] In this way, along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases.

[0094] The cross-sectional areas of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212 can be formed by the same cross section. The cross section is perpendicular to the axial direction of the spray hole 121. The axial direction of the spray hole 121 can be referred to as the Z direction, and the Z direction is used to replace the axial direction of the spray hole 121 in the following description.

[0095] It should be understood that, generally, when a liquid flows in a pipe, the flow rate of the liquid is inversely proportional to the cross-sectional area of ​​the pipe.

[0096] Since the spray hole 121 can also be regarded as a kind of pipe, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases along the flow direction of the liquid in the spray hole 121. Therefore, when the liquid flows in the liquid inlet section 1211, the flow velocity of the liquid increases continuously in the process of flowing in the liquid inlet section 1211. When the flow velocity of the liquid increases to a critical point in the liquid inlet section 1211, the flow velocity will not increase any more. At the critical point, the velocity of the fluid is greater than the speed of sound.

[0097] When the velocity of the fluid is greater than the speed of sound, the above-mentioned inverse proportionality between the flow velocity and the cross-sectional area of ​​the liquid is no longer applicable, but just the opposite. The larger the cross-sectional area, the faster the flow velocity of the liquid. Since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, when the liquid enters the liquid outlet section 1212, the liquid continues to accelerate and becomes supersonic, so that the flow velocity of the liquid can be instantly increased when the liquid is sprayed out through the spray hole 121. For the spray hole 121, the flow velocity is proportional to the pressure. Therefore, when the flow velocity of the liquid increases instantly, the pressure of the liquid also increases instantly, which can effectively rinse the clothes in the inner drum 50 and improve the cleaning effect.

[0098] At the same time, since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, the liquid has a larger spraying area when it is sprayed to the inner drum 50 through the liquid outlet section 1212, so that the liquid sprayed to the inner drum 50 through the spray hole 121 can cover a large area and rinse the clothes in the inner drum 50, which can efficiently wash the clothes and improve the cleaning effect.

[0099] In addition, the liquid sprayed by the spray head 120 to the inner drum 50 has a higher pressure and a larger spraying area, and part of the door body 30 usually protrudes toward one side of the inner drum 50, and the door seal 60 is located on the peripheral side of the protruding part of the door body 30. Therefore, the liquid sprayed by the spray head 120 to the inner drum 50 can not only flush the inner drum 50 over a larger area, but also flush the door body 30, the door seal 60, etc. over a larger area, so that the inner drum 50, the door seal 60, the door body 30, etc. are effectively flushed to avoid impurities such as foam generated by detergent from remaining in the inner drum 50, the door seal 60, and the door body 30, thereby improving the cleaning effect and ensuring the health of users.

[0100] In some embodiments, when the liquid inlet pipeline is a circulation pipeline 90, the liquid (such as washing water) in the inner drum 50 and the inner and outer drums 40 can be sprayed into the inner drum 50 through the spray hole 121, effectively washing the clothes in the inner drum 50, so that the clothes can be better soaked, so that the liquid can better disperse the stains attached to the surface of the clothes, thereby improving the cleaning effect. In addition, the liquid can be sprayed on the clothes through the spray head 120, and the liquid can also be hit on the clothes, effectively reducing the entanglement between the clothes, improving the cleaning effect, and at the same time, protecting the quality of the fabric of the clothes.

[0101] It should be noted that when the liquid inlet pipeline is a circulation pipeline 90, on the basis of achieving the same cleaning effect, compared with the clothing processing equipment in the related technology, the clothing processing equipment 10 of the present application has an improved cleaning effect. Therefore, the clothing processing equipment 10 of the present application also has the characteristics of saving time, saving electricity and reducing energy consumption.

[0102] In some embodiments, when the liquid inlet pipeline is a water inlet pipeline, the liquid in the liquid inlet pipeline can be water flowing into the water inlet pipeline from an external water source. The water inlet pipeline includes a water inlet pipe, a water inlet valve and a water inlet pipe branch. The water inlet pipe is connected to an external water source, and the water inlet valve is arranged between the water inlet pipe and the water inlet pipe branch. The water in the water inlet pipe can enter the water inlet pipe branch through the water inlet valve, and the water outlet end of the water inlet pipe branch is connected to the spray assembly 100. The water flowing through the water inlet pipe branch can bring detergent into the inner drum 50, and spray into the inner drum 50 through the spray hole 121, which can also better soak the clothes, thereby improving the washing effect. At the same time, when the water in the water inlet pipeline can be sprayed into the inner drum 50 through the spray hole 121, it can also effectively reduce the entanglement between clothes, improve the washing effect, and protect the quality of the fabric of the clothes.

[0103] It should be noted that the connection between the water inlet pipe, the water inlet valve and the water inlet pipe branch can be determined according to the structure of the clothing processing device 10 in the relevant technology, and will not be repeated in this application.

[0104] The structure of the clothes processing device 10 is further described below by taking the liquid inlet pipeline as the circulation pipeline 90 as an example.

[0105] See again Figure 1 As shown, in some embodiments, the laundry processing device 10 may further include a connecting device. The connecting device may be a three-way valve or the like. The connecting device is disposed in the housing 20. The connecting device may selectively connect the water outlet of the drain pump 70 to the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80.

[0106] When the liquid in the inner drum 50 and the outer drum 40 needs to be circulated and sprayed, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80. When the drain pump 70 is started, the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the circulation pipeline 90 and directly reach the spray head 120. The liquid sprayed from the spray head 120 can wash the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30, and the door seal 60.

[0107] When it is necessary to drain the liquid in the inner cylinder 50 and the outer cylinder 40 to the outside of the housing 20, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the drain pipe 80. When the drain pump 70 is started, the drain pump 70 can pump the liquid in the inner cylinder 50 and the outer cylinder 40 into the drain pipe 80, and the liquid can be discharged to the outside of the housing 20 through the drain pipe 80.

[0108] It should be noted that the structure of the communication device can be determined according to the structure of the clothing processing device 10 in the related art, and will not be described in detail in this application.

[0109] During the washing, rinsing and dehydration process of the clothing processing device 10, the liquid in the liquid inlet pipeline can be sprayed out from the spray hole 121 at any time according to the program design of the clothing processing device 10 to flush the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30 and the door seal 60.

[0110] The structure of the first spray assembly is further described below.

[0111] Figure 8 Shows Figure 5 Cross-sectional view along CC direction.

[0112] See also Figure 8 As shown, in some embodiments, along the flow direction of the liquid in the spray hole 121:

[0113] The inner diameter of the liquid inlet section 1211 can gradually decrease, the inner diameter of the liquid outlet section 1212 can gradually increase, and the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends can be equal, so that along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases to form a contraction structure, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases to form an expansion structure.

[0114] Furthermore, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, the inner diameter of the spray hole 121 can smoothly transition between the liquid inlet section 1211 and the liquid outlet section 1212, so as to ensure that the liquid can flow to the liquid outlet section 1212 along the predetermined water flow direction. At the same time, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, a narrow channel is formed between the liquid inlet section 1211 and the liquid outlet section 1212 of the spray hole 121, and when the liquid flows to the narrow channel through the liquid inlet section 1211, the flow rate of the liquid is at the critical point mentioned above.

[0115] See also Figure 8 As shown, when the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal:

[0116] The liquid inlet section 1211 may be directly connected to the liquid outlet section 1212 .

[0117] Alternatively, when the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal:

[0118] The spray hole 121 may also have a connecting section, and the liquid inlet section 1211 and the liquid outlet section 1212 are connected in the connecting section. Along the flow direction of the liquid in the spray hole 121, the inner diameters of the connecting section are equal, and the inner diameter of the connecting section is equal to the minimum inner diameter of the liquid inlet section 1211 and the liquid outlet section 1212, so that the inner diameters of the hole wall of the spray hole 121 at the liquid inlet section 1211 and the liquid outlet section 1212 can smoothly transition with the connecting section to ensure that the liquid can flow to the liquid outlet section 1212 along the established water flow direction.

[0119] Furthermore, by directly connecting the liquid inlet section 1211 and the liquid outlet section 1212 , or by providing a connecting section, the structure of the spray hole 121 can be made more diversified to meet the design requirements of different spray heads 120 for the spray hole 121 .

[0120] Compared with the setting of the connecting section, when the liquid inlet section 1211 is directly connected to the liquid outlet section 1212, the liquid pressure is instantly increased, the spraying area is increased, and the length of the spray hole 121 in the Z direction can be reduced, which is beneficial to reducing the size of the spray head 120 in the Z direction and realizing the miniaturization of the spray head 120.

[0121] Fig. 9 and Fig.10 The schematic diagrams are shown respectively Figure 4 Schematic diagram of the structure of the middle shower head 120 at different viewing angles.

[0122] See also Fig. 9 and Fig.10As shown, in some embodiments, the spray head 120 may have a plurality of spray holes 121. The plurality of spray holes 121 may be provided on the side of the spray head 120 facing the inner cylinder 50, so that the liquid in the liquid inlet pipeline is sprayed into the inner cylinder 50 through the spray holes 121. At the same time, by providing the plurality of spray holes 121, the spray area can be further expanded, so as to obtain a better cleaning effect and a flushing effect on the inner cylinder 50, the door seal 60, the door body 30, etc.

[0123] For example, the number of the spray holes 121 may be two, three, four, etc.

[0124] Fig. 9 and Fig.10 Four spray holes 121 are shown in FIG. The four spray holes 121 may include but are not limited to being arranged in a "Y" shape on the side of the spray head 120 facing the inner cylinder 50. For example, the four spray holes 121 may also be evenly arranged along the circumference of the spray head 120 on the side of the spray head 120 facing the inner cylinder 50.

[0125] In some embodiments, the spray head 120 may also have one spray hole 121. Compared with multiple spray holes 121, when the size of the spray head 120 is the same, the size of the spray hole 121 can be enlarged, which can also expand the spraying area, and obtain a better cleaning effect and a flushing effect on the inner cylinder 50, the door seal 60, the door body 30, etc.

[0126] See again Figure 3 As shown, in some embodiments, the spray assembly 100 may further include a spray pipe 110. The spray pipe 110 is connected to the water outlet end of the liquid inlet pipeline.

[0127] The spray assembly 100 may further include a fixing member 130. The spray pipe 110 may be connected to the fixing member 130. The spray pipe 110 may be connected to the fixing member 130 by a detachable manner such as a buckle or a thread, or the spray pipe 110 may be integrally connected to the fixing member 130 to form a structural member.

[0128] The fixing member 130 may have a connecting hole 131. The spray head 120 is mounted on the fixing member 130, and the spray head 120 is connected to the spray pipe 110 through the connecting hole 131. In this way, the spray head 120 can be mounted on the water outlet of the liquid inlet pipeline through the fixing member 130 and the spray pipe 110. At the same time, the spray head 120 can also be connected to the water outlet of the liquid inlet pipeline through the connecting hole 131 and the spray pipe 110, so that the liquid in the liquid inlet pipeline can enter the spray head 120 through the spray pipe 110 and the connecting hole 131, and finally spray the liquid to the inner cylinder 50 through the spray hole 121.

[0129] In some embodiments, the spray pipe 110 can be fixed to the outlet end of the liquid inlet pipeline by means of clamping, threading, welding, etc., and communicated with the outlet end of the liquid inlet pipeline. Similarly, the spray pipe 110 can also be connected to the fixing member 130 by means of clamping, threading, welding, etc.

[0130] In some embodiments, when the shower head 120 is mounted on the fixing member 130, the shower head 120 may not rotate relative to the fixing member 130, that is, the shower head 120 always sprays in the same direction. For example, the shower head 120 may be mounted on the fixing member 130 by welding, clamping, etc.

[0131] In some embodiments, when the spray head 120 is mounted on the fixing member 130, the spray head 120 can also rotate relative to the fixing member 130, so as to rotate the spray head 120 to change the spray direction of the spray head 120, further expand the spray area of ​​the spray head 120, so as to obtain a just cleaning effect and a flushing effect on the inner cylinder 50, the door seal 60, the door body 30, etc. For example, the spray head 120 can be mounted on the fixing member 130 by means of a clamping connection, a threaded connection, etc.

[0132] Fig.11 Shows Figure 1 Enlarged view at D.

[0133] See also Fig.11 As shown, in some embodiments, the spray assembly 100 can be arranged on the door seal 60 and located on the side of the door seal 60 facing the top of the housing 20, so as to realize the installation of the spray assembly 100 in the housing 20. Among them, the spray head 120 can be exposed on the inner side of the door seal 60, so that the liquid can be sprayed into the inner cylinder 50 through the spray hole 121. At the same time, the user can see the spray head 120 from the side facing the door seal 60, so that the water flow sprayed by the spray head 120 has the characteristic of visualization, so that the user can directly see the water flow effect sprayed by the spray head 120.

[0134] It should be noted that the inner side of the door seal 60 can be understood as the side of the door seal 60 facing the tube opening of the outer tube 40 along the radial direction of the outer tube 40 .

[0135] In some embodiments, the spray pipe 110 can be passed through and fixed on the door seal 60, and the water outlet end of the spray pipe 110 can be bent toward the side of the inner cylinder 50 relative to the rest of the spray pipe 110, so that when the spray head 120 is installed on the water outlet end of the spray pipe 110 through the fixing member 130, the spray head 120 can be located on the side of the door seal 60 facing the inner cylinder 50.

[0136] It should be noted that the fixing method of the spray pipe 110 on the door seal 60 can be determined according to the structure of the existing clothing processing device 10, and will not be described in detail in this application.

[0137] In addition to the first type of spray assembly mentioned above, the embodiment of the present application also provides a second type of spray assembly.

[0138] The difference from the first spray assembly is that the second spray assembly has multiple hole groups on the spray head 120, and the multiple hole groups produce different water flow effects during the washing and rinsing process of the clothing processing device 10. The user can rotate the spray head 120 according to the different types of clothes to select a hole group that is suitable for the type of clothes to be connected to the spray pipe 110, thereby producing a water flow effect that is suitable for the type of clothes, and washing, rinsing, etc. the clothes.

[0139] The differences of the second spray assembly are further described below in conjunction with the accompanying drawings.

[0140] Fig.12 and Fig.13 The schematic diagrams of the structure of the second spray assembly at different viewing angles when the first hole group 122 is connected to the spray pipe 110 are respectively illustrated. Fig.14 and Fig.15 The schematic diagrams of the structure of the second spray assembly provided in the embodiment of the present application at different viewing angles when the second hole group 123 is connected to the spray pipe 110 are respectively illustrated.

[0141] See also Figures 12 to 15 As shown, in some embodiments, the shower head 120 may have a plurality of hole groups on the side facing the inner barrel 50. The plurality of hole groups may include a first hole group 122 and a second hole group 123. The first hole group 122 and the second hole group 123 both have spray holes 121. The number of spray holes 121 in the second hole group 123 may be greater than the number of spray holes 121 in the first hole group 122.

[0142] Fig.16 yes Fig.13 Cross-sectional view in EE direction, Fig.17 yes Fig.15 Cross-sectional view in the FF direction.

[0143] See also Fig.16 and Fig.17As shown, when the number of the spray holes 121 in the second hole group 123 can be greater than the number of the spray holes 121 in the first hole group 122, the size of the spray holes 121 in the second hole group 123 can be smaller than the size of the spray holes 121 in the first hole group 122. The size of the spray hole 121 can include but is not limited to the inner diameter of the spray hole 121. The inner diameter of the spray hole 121 can include but is not limited to the inner diameter of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212.

[0144] Since the water flow effect generated by the hole group is related to the size of the spray hole 121, the larger the size of the spray hole 121, the more high-pressure liquid can be generated when the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 through the hole group. In addition, the water flow effect generated by the hole group is also related to the size of the spray hole 121. The more the number of spray holes 121 in the hole group, the more dispersed the water flow generated when the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 through the hole group, and the lower the pressure.

[0145] Therefore, by limiting the size and number of the spray holes 121 in the second hole group 123 and the first hole group 122, when the liquid in the liquid inlet pipeline is sprayed to the inner drum 50 through the first hole group 122 or the second hole group 123, two different water flow effects can be generated, so that the spray head 120 can generate a water flow efficiency adapted to the type of clothing, and wash, rinse, etc. the clothing.

[0146] The water flow effect generated by the first hole group 122 is more concentrated and the water flow pressure is greater, while the water flow effect generated by the second hole group 123 is more dispersed and the water flow pressure is smaller. The water flow generated by the first hole group 122 is suitable for washing clothes that require strong water flow for washing. The water flow generated by the second hole group 123 is suitable for washing clothes that require less water pressure.

[0147] For example, the first hole group 122 may have one spray hole 121, and the second hole group 123 may have two, three or four spray holes 121. Since the first hole group 122 has one spray hole 121, a single stream of water may be generated when the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 via the first hole group 122. When the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 via the second hole group 123, multiple streams of water with relatively low pressure may be generated.

[0148] The structure of the laundry processing device 10 is further described below by taking an example in which the first hole group 122 has one spray hole 121 and the second hole group 123 has four spray holes 121 .

[0149] In some embodiments, the spray assembly 100 may have a spray hole 126. The liquid in the liquid inlet pipeline may also be sprayed to the inner cylinder 50 through the spray hole 126 to expand the spraying area of ​​the spray assembly 100, thereby expanding the spraying area of ​​the spray assembly 100.

[0150] In addition to the spray area of ​​the spray hole 121, the spray area of ​​the spray assembly 100 may also include the spray area of ​​the spray hole 126. Accordingly, the spray area of ​​the spray assembly 100 may include the area occupied by the spray area of ​​the spray hole 121 and the spray area of ​​the spray hole 126.

[0151] Fig.18 and Fig.19 The schematic diagram shows the structure of the second spray assembly at different viewing angles when the third hole group 124 is connected to the spray pipe 110 . Fig. 20 Shows Fig.19 Cross-sectional view in the GG direction.

[0152] See also Fig.18 and Fig.19 As shown, in some embodiments, the spray assembly 100 may further include an insert 125 .

[0153] See also Fig. 20 As shown, the shower head 120 may have an embedding hole. The embedding element 125 is embedded in the embedding hole, and the circumferential outer wall of the embedding element 125 and the hole wall of the embedding hole may together form a spray hole 126, so that the liquid in the liquid inlet pipeline can be sprayed from a circle around the circumference of the embedding element 125 into the inner drum 50, so as to form a closed waterfall-like water flow effect around the circumference of the embedding element 125. On the basis of the first hole group 122 and the second hole group 123, the diversity of the water flow effect can be further enhanced to adapt to more types of clothing.

[0154] In some embodiments, the plurality of hole groups may further include a third hole group 124. The third hole group 124 may have at least one spray hole 126. Through the arrangement of the first hole group 122, the second hole group 123 and the third hole group 124 in the plurality of hole groups, the laundry treatment device 10 can generate a plurality of different water flow effects during washing, rinsing and other procedures.

[0155] The pressure of the water flow generated by the spray holes 126 is lower than the pressure of the water flow generated by the second hole group 123 . Therefore, the water flow generated by the third hole group 124 is suitable for washing clothes that require gentle water flow.

[0156] For example, the third hole group 124 may have one, two, or the like spray holes 126. Each spray hole 126 may be provided with a corresponding insert 125. The structure of the laundry processing device 10 is further described below by taking one spray hole 126 as an example.

[0157] For example, the insert 125 may be a structural member such as a screw or a bolt that can be installed on the shower head 120 by screwing.

[0158] See also Fig.19As shown, in the second spray assembly, the spray head 120 can be rotated relative to the fixing member 130 so that the spray pipe 110 is connected to one of the multiple hole groups, so that the user can rotate the spray head 120 according to the demand of the clothes for water flow, and select one of the hole groups to be connected to the spray pipe 110, so that when the clothing processing device 10 is in the washing, rinsing and other programs, the water flow effect adapted to the washed clothes can be generated through the selected hole group.

[0159] For example, when the washed clothes require a gentle water flow, the user can rotate the spray head 120 to connect the third hole group 124 with the spray pipe 110; when the washed clothes require multiple streams of water with lower pressure, the user can rotate the spray head 120 to connect the second hole group 123 with the spray pipe 110; when the washed clothes require a strong water flow, the user can rotate the spray head 120 to connect the first hole group 122 with the spray pipe 110.

[0160] It should be noted that, in addition to the demand for water flow by the clothes, the user can also select different hole groups to be connected to the spray pipe 110 according to different selected programs, so as to produce different water flow effects.

[0161] See also Fig.19 As shown, in some embodiments, the shower head 120 may have a buckle portion 127. The buckle portion 127 may be clamped on a side of the fixing member 130 facing the shower pipe 110, and the shower head 120 can rotate relative to the fixing member 130, so that the user can rotate the shower head 120.

[0162] See also Fig.19 and Fig. 20 As shown, in some embodiments, the side of the fixing member 130 facing the shower head 120 may have a deformable protrusion 132. The protrusion 132 is located at the edge area of ​​the fixing member 130. The shower head 120 may have a positioning portion 129 on the side facing the fixing member 130 to engage the protrusion 132. The positioning portion 129 is located at the edge area of ​​the shower head 120.

[0163] See also Fig.18 As shown, the shower head 120 may be provided with a positioning portion 129 at a position corresponding to each hole group. The positioning portion 129 may be a groove on the shower head 120 or other structure capable of engaging the protrusion 132. The positioning portions 129 may be evenly distributed along the circumference of the shower head 120. When the shower head 120 is rotated relative to the fixing member 130 until the protrusion 132 is engaged in one of the positioning portions 129, the shower pipe 110 may be connected to one of the hole groups, and the hole group connected to the shower pipe 110 corresponds to the positioning portion 129 engaged with the protrusion 132.

[0164] In this way, when the shower head 120 rotates and the protrusion 132 has not rotated to the positioning portion 129, the shower head 120 will squeeze the protrusion 132 so that the protrusion 132 can be deformed toward one side of the shower pipe 110. When the protrusion 132 rotates to the positioning portion 129, the squeezing of the protrusion 132 by the shower head 120 disappears, and the protrusion 132 is clamped in the positioning portion 129, so that the hole group corresponding to the positioning portion 129 can be connected to the shower pipe 110. When the protrusion 132 rotates to the next positioning portion 129, the protrusion 132 will be deformed again under the squeezing of the shower head 120 until the protrusion 132 is clamped in the next positioning portion 129.

[0165] Therefore, by rotating the spray head 120, the protrusion 132 can be sequentially engaged with each positioning portion 129, and each hole group can be positioned, so that during the rotation process, each hole group can be sequentially connected to the spray pipe 110 to obtain a variety of different water flow effects.

[0166] See also Fig.19 As shown, in some embodiments, the fixing member 130 may be provided with a cantilever 133. The free end of the cantilever 133 faces the edge area of ​​the fixing member 130, and the side of the free end facing the spray head 120 may be provided with a protrusion 132, so that the protrusion 132 is arranged at the edge area of ​​the fixing member 130. At the same time, before the protrusion 132 rotates to the positioning portion 129, the spray head 120 will squeeze the protrusion 132, so that the cantilever 133 is deformed toward one side of the spray pipe 110, and the protrusion 132 is driven to deform toward one side of the spray pipe 110 at the same time, so as to ensure that the protrusion 132 can be deformed. When the protrusion 132 rotates to the positioning portion 129, the squeezing of the protrusion 132 by the spray head 120 disappears, and the protrusion 132 is reset toward one side of the spray head 120, and the cantilever 133 is driven to reset toward one side of the spray head 120 at the same time.

[0167] Alternatively, in some embodiments, the protrusion 132 may also be a flexible protrusion on the fixing member 130. In this case, while the protrusion 132 is deformed and snapped onto the positioning portion 129, there is no need to provide the cantilever 133 on the fixing member 130, which can simplify the structure of the fixing member 130.

[0168] The spray head 120 may be circular or square, etc. The structure of the clothes processing device 10 is further described below by taking the spray head 120 being circular as an example.

[0169] See also Fig.18As shown, in some embodiments, along the radial direction of the shower head 120 , the protrusion 132 may be opposite to the connecting hole 131 of the fixing member 130 , and the protrusion 132 and the connecting hole 131 are located on both sides of the shower head 120 in the radial direction, so that the protrusion 132 is arranged at the edge area of ​​the fixing member 130 .

[0170] It should be noted that, along the radial direction of the shower head 120 , the protrusion 132 may be opposite to the connecting hole 131 of the fixing member 130 , which can be understood as that along the radial direction of the shower head 120 , the protrusion 132 and the connecting hole 131 are arranged opposite to each other.

[0171] When the shower head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in one of the positioning portions 129 , the hole group connected to the shower pipe 110 can be connected to the shower pipe 110 through the connecting hole 131 .

[0172] See also Fig.18 As shown, along the radial direction of the shower head 120 , each hole group may be provided with a corresponding positioning portion 129 , and each hole group and the corresponding positioning portion 129 may be distributed on both sides of the shower head 120 in the radial direction.

[0173] The structure of the laundry processing device 10 is further described below by taking three hole groups as an example.

[0174] For ease of description, the positioning portion 129 corresponding to the first hole group 122 is defined as a first positioning portion 1291 , the positioning portion 129 corresponding to the second hole group 123 is defined as a second positioning portion 1292 , and the positioning portion 129 corresponding to the third hole group 124 is defined as a third positioning portion 1293 .

[0175] See also Fig.12 , Fig.13 and Fig.16 As shown, when the spray head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in the first positioning portion 1291 , it means that the first hole group 122 is selected, and the first hole group 122 can be connected to the spray pipe 110 through the connecting hole 131 .

[0176] See also Fig.14 , Fig.15 and Fig.17 As shown, when the spray head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in the second positioning portion 1292 , it means that the second hole group 123 is selected, and the second hole group 123 can be connected to the spray pipe 110 through the connecting hole 131 .

[0177] See also Figures 18 to 20As shown, when the spray head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in the third positioning portion 1293 , it means that the third hole group 124 is selected, and the third hole group 124 can be connected to the spray pipe 110 through the connecting hole 131 .

[0178] See also Fig.18 As shown, the centers of the first positioning portion 1291, the second positioning portion 1292 and the third positioning portion 1293 can be located on the first circumference. When the shower head 120 rotates relative to the fixing member 130, the first circumference can serve as a rotation track of the protrusion 132, so that when the shower head 120 rotates relative to the fixing member 130, the protrusion 132 can be engaged in any positioning portion 129.

[0179] Correspondingly, the centers of the first hole group 122, the second hole group 123, and the third hole group 124 may also be located on the second circumference. When the shower head 120 rotates relative to the fixing member 130, the second circumference may serve as a rotation track of the center of the connecting hole 131, so that when the shower head 120 rotates relative to the fixing member 130, the center of any hole group may coincide with the center of the connecting hole 131, so that any hole group may be connected to the shower pipe 110 through the connecting hole 131.

[0180] See also Fig. 20 As shown, in some embodiments, the spray assembly 100 may further include a seal 134. The seal 134 may be a sealing ring or other sealing structure. The seal 134 is disposed at the periphery of the communication hole 131 to seal the fixing member 130 and one of the hole groups. By providing the seal 134, the gap between the selected hole group and the fixing member 130 in the communication hole 131 can be sealed to prevent the liquid flowing through the communication hole 131 from entering the unselected hole group and affecting the water flow effect of the spray head 120.

[0181] In some embodiments, a portion of the seal 134 may be embedded on the side of the fixing member 130 facing the shower head 120 to achieve installation of the seal 134 on the fixing member 130. Alternatively, in other embodiments, the seal 134 may also be installed on the side of the fixing member 130 facing the shower head 120 by bonding or the like.

[0182] See also Fig.16 , Fig.17 and Fig. 20 As shown, the side of the shower head 120 away from the fixing member 130 may have a plurality of protrusions 128. The number of protrusions 128 corresponds to the number of hole groups and corresponds one to one, and each protrusion 128 is provided with a hole group so that each hole group can be provided on the corresponding protrusion 128. In addition, when the user rotates the shower head 120, the protrusion 128 can be acted on, so that the user can apply force to the shower head 120, thereby rotating the shower head 120.

[0183] The projection areas of the protrusions 128 on the shower head 120 may be equal, that is, the areas of the holes in the shower head 120 may be equal. The shape of the end of the protrusion 128 facing the fixing member 130 may match the shape of the communication hole 131.

[0184] It should be noted that the “shape of A matches the shape of B” mentioned in the present application can be understood as the shape of A being the same as or similar to the shape of B. For example, “the shape of the end of the protrusion 128 facing the fixing member 130 can match the shape of the connecting hole 131” can be understood as the shape of the end of the protrusion 128 facing the fixing member 130 can be the same as or similar to the shape of the connecting hole 131. If there are similar descriptions below, this understanding can be made.

[0185] When the shape of one end of the protrusion 128 facing the fixing member 130 can match the shape of the connecting hole 131, the structure of the sealing member 134 can also match the shape of the connecting hole 131, so that the sealing member 134 can better seal the gap between the selected hole group and the fixing member 130 in the connecting hole 131.
