Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically to an adjustable spray device and cleaning equipment. Background Technology

[0002] Cleaning equipment, such as washing machines, is a widely used household cleaning appliance that can automatically wash, rinse, spin-dry, and self-clean clothes. It can also set various washing programs such as quick wash, mixed wash, wool wash, down wash, and children's clothes wash for different clothing materials and washing needs. However, the various washing programs of washing machines are usually achieved by changing water temperature, washing time, spin speed, washing action, and washing intensity. Although this can meet the adaptability to different clothing materials and washing needs, the water jet nozzles of existing washing machines are usually designed with a fixed water jet pattern, such as a fixed shape nozzle or a simple arrangement of water jet holes. Due to the uniformity of the water jet shape and intensity of the fixed nozzle or water jet hole, the washing machine still cannot achieve the best washing effect for clothes. Utility Model Content

[0003] In view of the shortcomings of the prior art, the present invention provides an adjustable spray device and a cleaning device including the adjustable spray device to improve the technical problem that the water flow shape and spray intensity of the fixed nozzle or spray hole of the existing washing machine are uniform and cannot achieve the best washing effect.

[0004] To achieve the above and other related objectives, a first aspect of this utility model provides an adjustable spraying device, comprising a housing, a nozzle, a spray adjustment section, and a drive mechanism. The nozzle is fixedly mounted on the housing. The spray adjustment section is mounted on the nozzle and / or the housing, and is located in the spray path of the nozzle. The drive mechanism is mounted on the housing and drives the shape and / or position of the spray adjustment section to change, thereby adjusting the state of the liquid sprayed from the nozzle.

[0005] The beneficial effects of this design are as follows: by setting a spray adjustment part on the spray path of the nozzle, and under the driving action of the drive mechanism, the state of the liquid sprayed from the nozzle can be adjusted, such as the direction, pressure and spray area, thereby realizing the diverse adjustment of water jet intensity, shape and spray area, enhancing the adaptability to washing different clothes, improving washing efficiency, reducing damage to clothes, and achieving the best washing effect.

[0006] In one embodiment of the adjustable spray device of this utility model, the driving mechanism includes an adjusting cylinder and a first driving device. The adjusting cylinder is rotatably mounted on the housing. The first driving device is mounted on the housing and drives the adjusting cylinder to rotate to change the shape and / or position of the spray adjusting part.

[0007] The beneficial effects of this design are as follows: by controlling the regulating drum through the first drive device, the flexibility of the regulating drum's rotation on the housing and the precision of the regulating drum's control over the spray regulating part are ensured. This allows for better matching of the washing status of the current washing equipment, precise control of the water flow regulation effect of the washing machine when washing different clothes, and reduced waste of water resources.

[0008] In one embodiment of the adjustable spray device of this utility model, the first driving device drives the adjusting cylinder to rotate through a transmission component.

[0009] The advantages of this configuration are as follows: Through the connection and drive of the transmission components, different transmission ratios can be selected as needed to achieve more precise drive control. Simultaneously, based on the housing structure design, the installation positions of the first drive device and the adjusting cylinder can be rationally arranged, optimizing the assembly structure. In one embodiment of the adjustable spray device of this utility model, the transmission component is a gear assembly. The first drive device drives the adjusting cylinder to rotate through the gear assembly. The gear assembly includes a first gear and a second gear. The first gear is coaxially arranged with the adjusting cylinder, and the second gear meshes with the first gear under the drive of the first drive device to drive the adjusting cylinder to rotate.

[0010] The beneficial effects of this design are: the meshing transmission between the first and second gears enhances the transmission stability and compactness of the transmission structure, and reduces space occupancy.

[0011] In one embodiment of the adjustable spray device of this utility model, the first gear and the adjusting cylinder are an integral structure.

[0012] The advantages of this design are: by integrating the first gear and the adjusting cylinder into a single structure, it saves on assembly complexity, reduces the failure rate of parts during use, and further reduces the space occupied within the housing.

[0013] In one embodiment of the adjustable spray device of this utility model, the adjusting cylinder includes a cylinder body and a variable diameter plate. The cylinder body is rotatably mounted on the housing and is connected to the first driving device. The variable diameter plate is installed inside the cylinder body and presses the spray adjusting part to change the shape and / or position of the spray adjusting part.

[0014] The beneficial effects of this design are as follows: by placing the variable diameter plate inside the cylinder, the structure of the regulating cylinder becomes more compact, and the rotation of the cylinder drives the synchronous rotation of the variable diameter plate, making the compression adjustment response of the variable diameter plate to the injection regulating part more timely, and increasing the control accuracy of the injection regulating part.

[0015] In one embodiment of the adjustable spray device of this utility model, the spray adjustment part includes a mounting part and at least one squeezing part. The mounting part is mounted on the nozzle, and at least one squeezing part is mounted on the mounting part and located on at least one side of the spray path of the nozzle. The driving mechanism acts on the squeezing part to move closer to or further away from the nozzle.

[0016] The advantages of this design are: by directly acting on the squeezing part located on the nozzle spray path through the drive mechanism, a faster response to water flow can be achieved; and the direct installation of the mounting part and the nozzle eliminates the need to readjust the position of the squeezing part on the nozzle spray path.

[0017] In one embodiment of the adjustable spray device of this utility model, there are two extrusion parts, which are arranged opposite each other on both sides of the spray path of the nozzle.

[0018] The beneficial effects of this design are as follows: by setting the extrusion sections on both sides of the nozzle spray path, the water flow state can be adjusted only by the extrusion section, ensuring better water flow adjustment and dispersion effects, and avoiding the water flow adjustment direction from impacting the inner wall of the cylinder and changing the water spray state.

[0019] In one embodiment of the adjustable spraying device of this utility model, the mounting part and the two extrusion parts are an integral structure; a deformation guide groove is provided at the connection position between the extrusion part and the mounting part.

[0020] The beneficial effect of this design is that by setting a deformation guide groove, the connection between the mounting part and the extrusion part is relatively weak compared to other parts, which helps to guide the deformation of the extrusion part and thus facilitates more precise control of the water flow on the spray path.

[0021] In one embodiment of the adjustable spraying device of this utility model, the extrusion part includes an extrusion plate and a boss. The extrusion plate is mounted on the mounting part, and the boss is mounted on the extrusion plate and located on the side away from the spraying path of the nozzle. The driving mechanism drives the boss to move the extrusion plate closer to or away from the spraying path.

[0022] The advantages of this design are as follows: compared to the direct control of the extrusion plate structure by the drive mechanism, the drive mechanism can more easily control the deformation of the extrusion plate through the boss, and reduce the design thickness of the extrusion plate, so as to move the extrusion plate closer to or further away from the spray path, thereby improving the control effect of the drive mechanism on the extrusion plate.

[0023] In one embodiment of the adjustable spray device of this utility model, the spray adjustment part further includes an adjustment spring, which is fitted between the two extrusion parts, and the side of the adjustment spring away from the nozzle extends to the outside of the extrusion part.

[0024] The beneficial effects of this design are: by setting an adjusting spring to reduce the impact on the extrusion part, the extrusion part is prevented from deforming or losing its adjusting effect due to prolonged water flow impact, or from being damaged, thus extending the service life of the extrusion part.

[0025] In one embodiment of the adjustable spraying device of this utility model, the driving mechanism includes an adjusting cylinder and a first driving device. The adjusting cylinder is rotatably mounted on the housing. The adjusting cylinder includes a cylinder body and a variable diameter plate. The first driving device is mounted on the housing and drives the adjusting cylinder to rotate, so as to drive the two extrusion parts to simultaneously approach the spraying path or simultaneously move away from the spraying path.

[0026] The beneficial effects of this design are as follows: by integrating the drive mechanism and the regulating cylinder onto the housing, the overall structural design becomes more compact, reducing the complexity of installation and assembly. The direct drive control of the cylinder by the first drive device, as well as the synchronous movement of the cylinder and the variable diameter plate, makes the drive response of the first drive device to the extrusion section more timely and the control precision more refined, thus better serving the adjustment of the water flow state.

[0027] In one embodiment of the adjustable spray device of this utility model, part of the nozzle is located inside the adjusting cylinder, and the spray adjusting part is installed on the nozzle located inside the adjusting cylinder.

[0028] The beneficial effect of this design is that by placing the spray adjustment unit on the nozzle located in the adjustment cylinder, the distribution of water flow can be optimized, so that even if the water flow state changes, its diffusion angle is still limited within the adjustment cylinder, thus avoiding excessive water flow diffusion that could lead to penetration into the cleaning equipment or housing.

[0029] In one embodiment of the adjustable spray device of this utility model, the adjustable spray device further includes a sealing mechanism, which is sealed and installed between the nozzle and the adjusting cylinder.

[0030] The beneficial effect of this design is that the sealing mechanism located between the nozzle and the regulating cylinder prevents water from backflowing or splashing into the cleaning equipment, thus avoiding equipment malfunction.

[0031] In one embodiment of the adjustable spray device of this utility model, a through hole is provided on the housing, the adjusting cylinder is rotatably installed in the through hole, and the spray path of the nozzle is parallel to the axial direction of the through hole.

[0032] The advantages of this design are as follows: the adjusting cylinder is installed inside the housing via a through-tube, and integrated with the drive mechanism located within the housing. This results in a more compact structure, saves overall installation space, and reduces the area occupied in the cleaning equipment. In one embodiment of the adjustable spray device of this utility model, the housing includes an outer shell and a top cover. The outer shell and the top cover are detachably connected. The nozzle is fixedly installed on the top cover. The adjusting cylinder is rotatably installed between the outer shell and the top cover. The first drive device is installed inside the outer shell.

[0033] The advantages of this design are as follows: the detachable installation structure of the housing can form a closed structure, preventing water from seeping into the housing and avoiding damage to the electrical components installed inside the housing, while also enabling the rotational assembly of the regulating cylinder and its drive connection with the first drive device.

[0034] In one embodiment of the adjustable spray device of this utility model, the adjustable spray device further includes a base, and the housing is movably connected to the base to adjust the orientation of the nozzle.

[0035] The beneficial effects of this design are: through the movable connection between the housing and the base, multiple angles can be adjusted between the adjustable spray device and the base, enabling the switching of the spray position, thereby achieving efficient directional cleaning of different positions of the cleaning equipment.

[0036] A second aspect of this utility model also provides a cleaning device, which includes the adjustable spray device described in any of the above claims.

[0037] The benefits of this design are as follows: by installing an adjustable spray device on the cleaning equipment, the water flow state at the outlet of the cleaning equipment can be adjusted, which makes up for the limitation that the water flow shape of the cleaning equipment cannot be adjusted, and can meet diverse washing needs, improve the washing efficiency of the cleaning equipment, and reduce water waste.

[0038] The adjustable spray device of this invention has a spray adjustment part set on the spray path of the nozzle. Under the driving action of the drive mechanism, the direction and pressure of the liquid sprayed from the nozzle can be adjusted by changing the shape or position of the spray adjustment part, thereby realizing the diverse adjustment of water jet intensity and shape, enhancing the adaptability to washing different clothes, improving washing efficiency, reducing damage to clothes, and solving the technical problem that the nozzle design structure of existing washing machines has a single water jet shape and intensity, which cannot achieve the best washing effect.

Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to those described, used, or made of materials in the embodiments of this invention.

[0053] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0054] To address the problems existing in the prior art, please refer to Figures 1 to 9This utility model provides an adjustable spray device and a cleaning device including the adjustable spray device. The adjustable spray device is installed at the nozzle of the cleaning device. A spray adjustment part 300 is provided on the spray path of the nozzle 200 of the adjustable spray device. By changing the shape or position of the spray adjustment part 300, the state of the liquid sprayed from the nozzle 200 can be adjusted. Therefore, it can improve the technical problem that the nozzle design structure of the existing cleaning device has a single water flow spray shape and intensity, which cannot achieve the best washing effect.

[0055] This utility model relates to an adjustable spray device installed on a cleaning device. It is used to adjust the state of the water flow sprayed from the outlet of the cleaning device. The adjustment of the water flow state includes, but is not limited to, adjustments of direction, pressure, and spray area, thereby achieving a better cleaning effect. This cleaning device can be a washing machine, dishwasher, etc., but is not limited to these. Taking a washing machine as an example, the adjustable spray device can be detachably installed at the nozzle of the washing machine or integrated into the nozzle structure of the washing machine, used to adjust the intensity and shape of the water spray at the washing machine's outlet. One or multiple adjustable spray devices can be installed, each positioned at different locations on the cleaning device to adjust the water supply to different parts.

[0056] Please see Figure 1 The adjustable spray device includes a housing 100, a nozzle 200, a spray adjustment unit 300, and a drive mechanism 400. The shape and structure of the housing 100 are not limited and can be optimized according to space requirements. While ensuring the installation and connection requirements of the components, it can be designed as a closed or semi-closed structure. The nozzle 200 is fixedly installed on the housing 100. The structure of the nozzle 200 includes, but is not limited to, a tube, a cone, or other rotating structures, as long as it can spray water into the cleaning equipment. The water inlet end of the nozzle 200 is connected to the water inlet or water inlet pipe of the washing machine, and the water flow is sprayed into the drum of the washing machine through the nozzle 200.

[0057] In this embodiment, the jet adjustment unit 300 is mounted on the nozzle 200 and located on the jet path of the nozzle 200, i.e., at the water outlet end of the nozzle 200. The jet adjustment unit 300 can be a structure capable of changing its shape or position, and the change in shape or position acts on the water flow at the water outlet end of the nozzle 200, thereby changing the state of the water flow at the water outlet end, i.e., water pressure, water flow direction, and water jet area. It should be noted that in other embodiments, the jet adjustment unit 300 may also be mounted only on the housing 100; or it may be mounted between the nozzle 200 and the housing 100, and connected to both the nozzle 200 and the housing 100 respectively, as long as it can satisfy the requirement of changing the water flow state on the jet path of the nozzle 200. The drive mechanism 400 is mounted on the housing 100 and drives the spray adjustment unit 300 to change its shape or position, thereby adjusting the direction and pressure of the water flow sprayed from the nozzle 200. That is, when the washing machine is washing clothes of different materials, the drive mechanism 400 changes one or both of the shape and position of the spray adjustment unit 300. The change in the shape or position of the spray adjustment unit 300 acts on the water flow spray path of the nozzle 200, adjusting factors such as the spray direction, spray pressure, and spray shape of the water flow to a state suitable for the washing requirements of the current material of the clothes. This achieves diverse adjustment of the water flow spray intensity and shape, enhances the adaptability of the washing machine to washing different clothes, improves the washing efficiency, and at the same time, changes in water flow intensity and state can reduce damage to special clothes and reduce water waste according to different washing states, achieving better washing results.

[0058] The drive control method of the adjustable spray device drive mechanism 400 of this utility model can be controlled by the washing control system of the cleaning equipment (not shown) or manually controlled by an external mechanical knob on the cleaning equipment (not shown); the washing control system of the cleaning equipment or the cleaning equipment is a conventional component in existing cleaning equipment, and its control method is also a conventional control method, so it will not be described in detail here.

[0059] To ensure that the water flow adjustment is optimally matched to the washing status of the current washing equipment, and to precisely control the water flow adjustment effect of the washing machine when washing different types of clothing, thus reducing water waste, please refer to the following embodiment of the adjustable spray device of this utility model. Figure 1The drive mechanism 400 includes an adjusting cylinder 410 and a first drive device 420. The adjusting cylinder 410 is rotatably mounted on the housing 100 and is used to change the shape or position of the spray adjusting part 300. The first drive device 420 is mounted on the housing 100 and serves as the power drive mechanism for the rotational movement of the adjusting cylinder 410. It drives the adjusting cylinder 410 to rotate, thereby changing the shape or position of the spray adjusting part 300. The first drive device 420 includes, but is not limited to, a motor or a combination of a motor and a reducer, to meet the requirements of providing rotational power to the adjusting cylinder 410 and precise control of the rotation angle. In this embodiment, the first drive device 420 can be communicatively connected to the washing control system of the washing equipment. The washing control system is the control module of the washing equipment. Based on the washing program selected for the clothes being washed in the washing machine, the control module controls the rotation angle and speed of the first drive device 420, controls the position of the adjusting cylinder 410, and thus changes the shape or position of the spray adjusting part 300. It should be noted that the washing control system or control module is a conventional control component of existing washing machines or cleaning equipment, used to control the washing machine to select different washing states through different programs; the communication control between the washing control system or control module and the first drive device 420 is also a conventional control method.

[0060] Furthermore, to ensure the accuracy of the rotation angle and speed of the first driving device 420, thereby achieving more precise water flow control, in this embodiment, the first driving device 420 can be a stepper motor to achieve precise rotation control of the regulating cylinder 410. However, those skilled in the art will understand that in other embodiments, the first driving device 420 can also be a servo motor.

[0061] In one embodiment of the adjustable spray device of this utility model, the rotation of the adjusting cylinder 410 can be directly driven by the first driving device 420, or it can be driven by the first driving device 420 through a transmission assembly. The transmission assembly includes, but is not limited to, gear transmission, chain transmission, and belt transmission. Considering the transmission stability and structural compactness of the transmission structure, please refer to [reference needed]. Figure 2In this embodiment, the transmission component is a gear assembly. The first drive device 420 drives the adjusting cylinder 410 to rotate through the gear assembly. The type and number of gears in the gear assembly are not limited, taking into account the reduction ratio and space occupancy. In this embodiment, the gear assembly includes a first gear 413 and a second gear 421. The first gear 413 is fixedly installed on the outside of the adjusting cylinder 410 and is coaxially arranged with the adjusting cylinder 410. The second gear 421 is installed at the output end of the first drive device 420. The first gear 413 and the second gear 421 are meshed together. Under the drive of the first drive device 420, the second gear 421 meshes with the first gear 413 to drive the adjusting cylinder 410 to rotate. This gear assembly facilitates the installation and transmission connection positioning of the adjusting cylinder 410 and the first drive device 420. The structural design of the first gear 413 and the second gear 421 can save installation space and has high stability while meeting the driving requirements well. Meanwhile, in order to improve the accuracy of the transmission ratio and make the rotation of the adjusting cylinder 410 more precise, thereby achieving fine adjustment and control, the first gear 413 adopts a large gear ring and the second gear 421 adopts a small gear.

[0062] To reduce assembly complexity and decrease the failure rate of components during use, in one embodiment of the adjustable spraying device of this utility model, the first gear 413 and the adjusting cylinder 410 are an integral structure, for example, an integral injection molding structure. After the adjusting cylinder 410 is installed and positioned in the housing 100, it precisely meshes with the first drive device 420, which is fixed in the installation position in the housing 100.

[0063] To reduce the overall structural dimensions of the adjustable spray device and achieve compact installation; please refer to Figure 3 and Figure 4In one embodiment of the adjustable spray device of this utility model, a through hole 130 is provided on the housing 100, and an adjusting cylinder 410 is rotatably installed in the through hole 130. The water outlet end of the nozzle 200 is located in the adjusting cylinder 410, so that the spray path of the nozzle 200 is parallel to the axial direction of the through hole 130, optimizing the distribution of water flow. This limits the diffusion angle of the water flow after adjustment by the spray adjusting part 300 to the radial range of the adjusting cylinder 410, especially during warm water washing, to avoid excessive diffusion of water flow or steam, ensuring the outlet water temperature and preventing steam from penetrating into the housing 100. In this embodiment, the housing 100 includes an outer shell 110 and an upper cover 120. The outer shell 110 and the upper cover 120 are detachably connected. The detachable connection method includes, but is not limited to, snap-fit ​​connection, plug-in connection, and bolt connection, as long as the connection and fixation of the outer shell 110 and the upper cover 120 can be achieved. In this embodiment, the outer shell 110 and the upper cover 120 are bolted together. A through hole 130 is formed through the outer casing 110 and the upper cover 120. A nozzle 200 is fixedly installed on the upper cover 120. An adjusting cylinder 410 is rotatably installed between the outer casing 110 and the upper cover 120, restricting its axial displacement; that is, the adjusting cylinder 410 is rotatably installed in the through hole 130. A first driving device 420 is installed inside the outer casing 110 and is connected to the adjusting cylinder 410 for transmission, allowing the adjusting cylinder 410 to rotate between the outer casing 110 and the upper cover 120. The detachable outer casing 110 and upper cover 120 facilitate the installation and connection of the first driving device 420 and the adjusting cylinder 410, while also forming a closed structure to prevent water seepage into the casing 100 and avoid damage to electrical components. Meanwhile, a wire groove hole 121 is also provided on the side of the upper cover 120 away from the through hole 130. When the upper cover 120 is installed with the outer shell 110, the wire groove hole 121 passes through the inner cavity of the outer shell 110 and serves as the through channel for the wiring of the first drive device 420, and avoids interference of the wiring layout with the rotation of the adjustment cylinder 410.

[0064] Please see Figure 4In one embodiment of the adjustable spray device of this utility model, the rotating installation method of the adjusting cylinder 410 in the through hole 130 is such that the outer wall of the adjusting cylinder 410 is sleeved in the inner cavity of the through hole 130 and has a gap for rotation. The first gear 413 is clamped between the outer shell 110 and the upper cover 120 to limit and fix the first gear 413. The tooth portion of the first gear 413 extends into the cavity portion of the outer shell 110 and meshes with the gear of the first drive device 420 located in the cavity. A first clamping platform is provided on the lower end face of the upper cover 120. 122. A height difference is formed between the first clamping platform 122 and the upper cover 120, so that during the rotation of the first gear 413, there is not too much contact area between its upper end face and the lower plane of the upper cover 120, which would cause frictional interference. The lower part of the first gear 413 corresponding to the position of the first clamping platform 122 is the second clamping platform 111, that is, the shell wall part of the outer shell 110, which supports the first gear 413. Then, the adjusting cylinder 410 is assembled onto the shell 100 by clamping, which facilitates the assembly of the first gear 413 and the second gear 421 located in the outer shell 110. It should be noted that in other embodiments, the adjusting cylinder 410 can also be rotatably installed in the through hole 130 by other structures, such as the inner ring of the bearing being sleeved on the outer wall of the adjusting cylinder 410 and the outer ring of the bearing being fitted against the through hole 130.

[0065] Please see Figures 4 to 5 In one embodiment of the adjustable spray device of this utility model, the nozzle 200 includes a tube body 210, a mounting plate 220, a sealing part 230, and a spray head 240. The tube body 210 has an internal channel for connecting to the spray head 240 for water flow. The diameter of the channel gradually decreases from the water inlet end of the tube body 210 to the water outlet end of the spray head 240 to increase the water flow velocity and improve the spraying effect. The mounting plate 220 is located on the outside of the tube body 210 and has a connecting hole. The nozzle 200 is mounted and connected to the upper cover 120 via the mounting plate 220. The sealing part 230 is located on the outside of the tube body 210 and between the adjusting cylinder 410 and the tube body 210. In this utility model, the sealing part 230 can be any suitable structure capable of independently preventing water backflow into the cleaning equipment, or it can be any suitable structure capable of installing other sealing components to prevent water backflow into the cleaning equipment. The nozzle head 240 is the water jetting end of the nozzle 200, i.e., the starting point of the water jetting path. A jet adjustment section 300 is mounted on the nozzle head 240. The tube body 210, sealing section 230, and nozzle head 240, all located below the mounting plate 220, are all located within the adjustment cylinder 410. In this embodiment, the tube body 210, mounting plate 220, sealing section 230, and nozzle head 240 are an integral injection-molded structure. The nozzle 200 can be made of plastic, such as ABS plastic, polyethylene, or polypropylene, or it can be made of metal.

[0066] For instructions on achieving water flow, please refer to [link / reference]. Figures 6 to 7 In one embodiment of the adjustable spray device of this utility model, the adjusting cylinder 410 includes a cylinder body 411 and a variable diameter plate 412. The cylinder body 411 is rotatably mounted on the housing 100. The outside of the cylinder body 411 is connected to the first driving device 420 through a transmission assembly, such as the first gear 413 in the above embodiment, which is located on the outside of the cylinder body 411. Figure 7 As shown, the variable diameter plate 412 smoothly changes the profile of the inner sidewall of the cylindrical part 411 to form a cam-like structure. The outer periphery of the variable diameter plate 412 is fixedly installed inside the cylindrical part 411. The inner sidewall of the variable diameter plate 412 abuts against the spray adjustment part 300. When the cylindrical part 411 rotates, the variable diameter plate 412 squeezes the spray adjustment part 300 to change the shape or position of the spray adjustment part 300, thereby adjusting the water flow on the spray path of the nozzle 200. In this embodiment, the variable diameter plate 412 and the cylindrical body 411 are integrally injection molded structures and contact the spray adjustment part 300. The outer ring of the variable diameter plate 412 is integrally injection molded into the inner cavity of the cylindrical body 411, and the inner ring of the variable diameter plate 412 is a variable diameter structure. When the variable diameter plate 412 rotates synchronously with the cylindrical body 411, the radial dimension of the contact position between the spray adjustment part 300 and the inner ring of the variable diameter plate 412 from the axis of the cylindrical body 411 changes with the compression of the variable diameter inner cavity of the variable diameter plate 412, thereby realizing water flow adjustment.

[0067] Please see Figures 8 to 9 In one embodiment of the adjustable spray device of this utility model, the spray adjustment part 300 includes a mounting part 310 and at least one squeezing part 320. The mounting part 310 is mounted on the nozzle 200, and at least one squeezing part 320 is mounted on the mounting part 310 and located on at least one side of the spray path of the nozzle 200. The squeezing part 320 can move closer to or away from the nozzle 200 when the driving mechanism 400 acts on it. Specifically, in this embodiment, the mounting part 310 is sleeved and mounted on the water outlet end of the nozzle 200, that is, the spray head 240 in the above embodiment. In the non-squeezing state, the squeezing part 320 is located on one side of the spray path of the nozzle 200. The squeezing part 320 is made of a material with a certain elastic deformation capability, including but not limited to rubber, plastic and other materials. Under the action of the adjustment cylinder 410 of the driving device 400, the squeezing part 320 is squeezed and deformed, moving closer to the water spray path of the nozzle 200, thereby changing the direction and intensity of the water flow. To ensure better water flow regulation and dispersion, and to prevent the water flow direction from impacting the inner wall of the cylinder 411 and thus altering the water jet state, this embodiment includes two extrusion sections 320, positioned opposite each other on either side of the nozzle 200's jet path. The nozzle 200's jet path flows through the gap between the two extrusion sections 320, ensuring that the water flow state is only affected by the adjustment of the extrusion sections 320.

[0068] Please see Figure 8 In this embodiment, the mounting part 310 and the two extrusion parts 320 are an integral structure. For example, the mounting part 310 and the two extrusion parts 320 are made of rubber. In order to ensure that the extrusion part 320 can deform in a specific direction when it is extruded by the regulating cylinder 410, a deformation guide groove 323 is provided at the connection position between the extrusion part 320 and the mounting part 310. The deformation guide groove 323 is provided on the extrusion part 320 away from the water jet path of the nozzle 200 and is located at the junction of the extrusion part 320 and the mounting part 310. The setting of the deformation guide groove 323 makes the connection position between the two relatively weak compared with other positions, which is beneficial to guiding the deformation of the extrusion part 320.

[0069] Please see Figures 8 to 9 To enable more precise extrusion control of the variable diameter plate 412, in one embodiment of the adjustable spray device of this utility model, the extrusion part 320 includes an extrusion plate 321 and a boss 322. In this embodiment, the extrusion plate 321 has a rectangular structure, which can meet the deformation requirements after extrusion. It should be noted that in other embodiments, the extrusion plate 321 can also have other shapes. The extrusion plate 321 is mounted on the mounting part 310, and a deformation guide groove 323 is provided on the outer side of the extrusion plate 321 at the connection position with the mounting part 310. The boss 322 is mounted on the extrusion plate 321 and is located on the side away from the spray path of the nozzle 200. The boss 322 is used to connect with the drive mechanism 400. The drive mechanism 400 drives the boss 322 to move the extrusion plate 321 closer to or away from the spray path. In this embodiment, the boss 322 is installed in the variable diameter cavity of the variable diameter plate 412. It contacts the variable diameter inner cavity. When the variable diameter plate 412 rotates with the cylinder part 411, the variable diameter inner cavity squeezes the two protrusions 322 together due to the change in radial size, touching the water jet path. As the gap between the squeezing plates 321 changes, the water outlet pattern of the nozzle 200 changes accordingly. The water flow at the outlet end of the nozzle 200 is directly sprayed onto the squeezing plate 321. With the variable diameter structure of the variable diameter plate 412 constantly adjusting the gap between the squeezing plates 321 on both sides, a variety of water flow patterns are formed to adapt to different washing requirements.

[0070] Please see Figures 8 to 9In one embodiment of the adjustable spray device of this utility model, in order to further absorb the impact force of the water flow, reduce the direct impact on the squeezing part 320, and prevent the squeezing part 320 from deforming or being damaged due to prolonged water flow impact, thereby extending the service life of the squeezing part 320, the spray adjustment part 300 also includes an adjustment spring 330. The adjustment spring 330 is fitted between the two squeezing parts 320 and is located on both sides of the spray path. The side of the adjustment spring 330 away from the nozzle 200 extends to the outside of the squeezing part 320. In this embodiment, by changing the first driving device 420 to control the rotation of the adjustment cylinder 410, the two squeezing parts 320 are driven to rotate, thereby squeezing the adjustment spring 330 located on both sides of the spray path. Due to the change in the gap of the adjustment spring 330, the water outlet pattern of the nozzle 200 changes accordingly, thereby realizing the adjustment of different water flow patterns. The adjusting spring 330 extends beyond the extrusion section 320, extending the flow path of the water on the adjusting spring 330. This avoids water flow instability caused by the radial length of the adjusting spring 330 being too short, and prevents the water from contacting and colliding with the variable diameter plate 412 when it is freely sprayed after leaving the plate surface of the adjusting spring 330. This reduces secondary changes in the water flow state due to collisions, thereby maintaining the washing effect of the water flow state after being adjusted by the adjusting spring 330. Meanwhile, in this embodiment, in order to simplify the assembly difficulty of the adjusting spring 330 on the extrusion part 320 and realize the detachable replacement of the adjusting spring 330, the adjusting spring 330 adopts a U-shaped structure. The closed end of the U-shaped structure is sleeved and installed on the water outlet end of the nozzle 200, and fixed on the nozzle 200 by the mounting part 310. The plates on both sides of the open end of the U-shaped structure are in contact with the two sides of the two sets of extrusion plates 321. Relying on the elastic deformation performance of the adjusting spring 330, the two sets of extrusion plates 321 can be vertically reset when the spray state does not need to be adjusted. The design of the adjusting spring 330 takes into account the durability and reliability of long-term use, and reduces wear and failure caused by frequent adjustment.

[0071] In one embodiment of the adjustable spraying device of this utility model, the drive mechanism 400 includes an adjusting cylinder 410 and a first drive device 420. The adjusting cylinder 410 is rotatably mounted on the housing 100. The adjusting cylinder 410 includes a cylinder part 411 and a variable diameter plate 412. The first drive device 420 is mounted on the housing 100 and drives the adjusting cylinder 410 to rotate, so as to drive the two extrusion parts 320 to simultaneously approach the spraying path or simultaneously move away from the spraying path.

[0072] In one embodiment of the adjustable spray device of this utility model, some nozzles 200 are located inside the regulating cylinder 410, and a spray regulating part 300 is installed on the nozzles 200 located inside the regulating cylinder 410. In this embodiment, in order to prevent the water flow sprayed from the water outlet end of the nozzle 200 from back-seeping into the housing 100 or the interior of the cleaning equipment along the regulating cylinder 410, the adjustable spray device also includes a sealing mechanism 500. The sealing mechanism 500 is sealed and installed between the nozzle 200 and the regulating cylinder 410 to block the water flow and prevent the water flow from back-seeping into other structures and affecting the working state of the equipment. In this embodiment, the sealing mechanism 500 adopts a sealing ring, which is sleeved on the sealing part 230 of the nozzle 200 in the above embodiment. The sealing ring seals and connects the sealing part 230 and the regulating cylinder 410 to prevent water back-seepage.

[0073] In one example of the adjustable spray device of this utility model, the adjustable spray device also has a base (not shown) on the outer shell; the shell 100 is movably connected to the base, and the base is fixedly connected to the cleaning equipment to adjust the orientation of the nozzle 200; the base allows the adjustable spray device to be angled, and the spray position can be easily switched by manual or automatic operation. Specifically, the movable connection between the shell 100 and the base includes, but is not limited to, rotational connection, push connection, or damping structure connection, as long as the rotation of the shell 100 relative to the base can be realized, thereby changing the position or orientation of the nozzle 200 on the shell 100; the setting of the base allows the adjustable spray device to perform directional and efficient cleaning of conventional parts of the cleaning equipment such as the inner wall of the drum, door seals, and door glass: thereby effectively cleaning the dirt and residual detergent on the door rubber ring and door glass, reducing the accumulation of dirt on the rubber ring and door glass, reducing the corrosion caused by detergent in contact with the rubber ring and door glass for a long time, slowing down the aging rate, extending the elasticity and service life of the rubber ring, inhibiting bacterial growth and secondary pollution, and ensuring the cleanliness of the cleaning equipment.

[0074] This utility model features an adjustable spray device with a spray adjustment section on the spray path of the nozzle. Driven by a driving mechanism, the shape or position of the spray adjustment section adjusts the direction and pressure of the liquid sprayed from the nozzle, thereby achieving diverse adjustments to the intensity and shape of the water jet. This addresses the technical problem of existing washing machines where the nozzle design results in a single water jet shape and intensity, failing to achieve optimal washing performance. Therefore, this utility model effectively overcomes some practical problems in the prior art, possessing high utilization value and practical significance. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
