DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0054] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0055] The sealing structure provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0056] First, the following noun concepts are described:

[0057] Material: refers to the substance that is specifically transported in the actual application scenario. The technical solution of this application is used to achieve sealing during the material transportation process.

[0058] In the embodiments of the present application, the physical state of the material can be liquid, solid particles, or a solid-liquid mixture. The type of material corresponds to the actual product. For example, for care equipment, the material can be a care product. For an electric toothbrush that can automatically replenish toothpaste, the material can be toothpaste. For some liquid delivery equipment, the material can be water, chemical solution, etc. The embodiments of the present application do not limit the specific physical state and specific type of the material. The specific properties of the material correspond to the actual needs of the product and do not affect the sealing principle of the above-mentioned sealing structure.

[0059] Material devices, devices related to material transportation, can be specifically divided into two main components of the equipment used for material transportation: material supply devices and material receiving devices, among which:

[0060] The material providing device mainly stores materials needed for use and provides a source of power for material transportation. For example, the material providing device may include a container for storing materials. The power source for material transportation may be, for example, a pushing device arranged in the container, which is used to push the material out of the container. The material providing device has an outlet, which refers to the end where the material is finally transported out of the material providing device. The material providing device may be a consumable container (or material container) for containing consumables (or materials), and the consumables may specifically be toothpaste, care products, etc.; or, the material providing device may be a suction device in an electric toothbrush, such as a pump or a motor including a hollow rotating shaft.

[0061] The material receiving device mainly receives materials, and uses the materials specifically or further transports the materials to other equipment or components. For example, the material receiving device may include a device for sucking and absorbing materials, such as a suction device with a piston component. The material receiving device may also include a device for using materials. For example, if the material in the above example is a care product, the device for using the material may be an electric massage head for applying the care product. For another example, if the material in the above example is toothpaste, the device for using the material may be an electric toothbrush for brushing teeth (which may include a toothbrush head, a control module for controlling the operation of the toothbrush head, a drive module, etc.); specifically, a material receiving device may be provided in the handle of the electric toothbrush, and the material receiving device and the material providing device for the material container may be provided in the handle of the electric toothbrush. The material receiving device and the material supply device are connected, that is, after the electric toothbrush handle is fixedly connected to the material container (such as a toothpaste bottle), the material receiving device and the material supply device are connected to each other through the material transmission channel, and the input end of the electric toothbrush receives the toothpaste transmitted from the toothpaste bottle; or, the electric toothbrush handle is provided with a material receiving device and a material supply device, for example, the material supply device is the pump exemplified above, and the material supply device is a motor including a hollow shaft connected to the output end of the pump, and the material is transmitted to the input end of the motor through the output end of the pump and then transmitted to the hollow shaft of the motor; or, the electric toothbrush handle is provided with a material supply device, and the brush head of the electric toothbrush is provided with a material receiving device, for example, the material supply device is a hollow motor shaft, and the material receiving device is the input end of the material channel of the brush head handle. The material receiving device has an inlet end, which refers to the end for receiving the material.

[0062] The material end may be the material outlet end of the material providing device, or may be the material inlet end of the material receiving device.

[0063] It should be noted that the examples given in the above explanations are only for a better understanding of the technical solution of the present application, and do not constitute a substantial limitation on the technical solution of the present application, that is, the above-mentioned materials, material providing devices, and material receiving devices can all be existing products, and can be flexibly selected according to the specific implementation scenario.

[0064] See also Figures 1 to 4 The embodiment of the present application provides a sealing structure, which can be applied not only to the field of sealing technology, but also to the field of personal care or electric toothbrush, including:

[0065] The body includes two opposite end surfaces (with Figures 1 to 4 Taking the illustrated scene as an example, it may include a first end surface 1, a second end surface 2) and a side surface 3 connecting the two end surfaces, that is, the side surface 3 is connected to the first end surface 1 and the second end surface 2;

[0066] A channel 4 is provided on the body. In actual application scenarios, one or more channels 4 for conveying materials can be provided according to actual needs. The channel 4 runs through the two end faces and forms an opening on each end face. Specifically, the channel 4 forms a first opening 41 on the first end face 1, and the channel 4 runs through the second end face 2 to form a second opening 42. A first sealing protrusion 5 surrounding the opening is provided on at least one end face. It can be understood that the first sealing protrusion 5 can be provided on one of the two end faces, or the first sealing protrusion 5 can be provided on both end faces. Figures 1 to 4 Taking the scenario shown as an example, a first sealing protrusion 5 is set on the first end face 1. The specific examples of the solution in this application are described using this scenario as an example. The situation in which the first sealing protrusion 5 is set on both end faces can be understood by referring to the situation in which the first sealing protrusion 5 is set on the first end face 1.

[0067] Specifically, a first sealing protrusion 5 is provided on the first end face 1 corresponding to each channel 4, and the first sealing protrusion 5 is provided to surround the first opening 41; in a specific implementation scenario, the shape of the first sealing protrusion 5 and the first opening 41 can be the same, for example, the first opening 41 is a circular opening, and the corresponding first sealing protrusion 5 is a circular ring structure, in which case the first sealing protrusion 5 is provided around the first opening 41, or the first opening 41 is a rectangular opening, and the corresponding first sealing protrusion 5 is a rectangular structure surrounding the first opening; the shape of the first sealing protrusion 5 and the first opening 41 can also be different, for example, the first opening 41 is a circular opening, and the corresponding first sealing protrusion 5 is a rectangular structure surrounding the circular first opening 41.

[0068] In the embodiment of the present application, the material device includes: a material providing device (not shown in the figure) and / or a material receiving device (not shown in the figure). In the embodiment of the present application, the case where the first end face 1 is opposite to the material conveying direction and the second end face 2 is in the same direction as the material conveying direction is taken as an example for explanation. Accordingly, after the material providing device, the material receiving device and the sealing structure are assembled, the material providing device is located on one side of the first end face 1 of the sealing structure, and the material receiving device is located on one side of the second end face 2 of the sealing structure; the first opening 41 can be referred to as the inlet of the channel 4, and the second opening 42 can be referred to as the outlet of the channel 4; of course, the material providing device can also be located on one side of the second end face 2 of the sealing structure, and the material receiving device can be located on one side of the first end face 1 of the sealing structure, in which case the second opening 42 is the inlet of the channel 4, and the first opening 41 is the outlet of the channel 4. Flexible processing can be performed according to the actual scenario; it can be understood that, based on the actual material conveying needs, one or more channels 4 can be set to meet the needs of one material conveying or multiple material conveying needs. For example Figures 1 to 3 The scene shown in FIG. 4 is a scene with two channels 4; optionally, the body can be designed as a ring structure, that is, Figures 1 to 3As shown in the figure, the middle hollow part can be used to accommodate other assembly parts. The present application does not specifically limit whether to set the hollow part and the shape of the hollow part, and can be flexibly designed according to the actual application scenario requirements.

[0069] The first opening 41 is used to communicate with the outlet end of the material providing device (not shown in the figure) when the sealing structure is assembled with the material providing device (not shown in the figure) and the material receiving device (not shown in the figure). The first sealing protrusion 5 is squeezed with the material end face of the outlet end of the material providing device to produce elastic deformation, that is, the sealing structure and the material end face of the outlet end of the material providing device are squeezed against each other by the force generated by the assembly, and then a tight fit is formed through the elastic deformation of the first sealing protrusion 5 to achieve an effective sealing effect. The second opening 42 is used to communicate with the inlet end of the material receiving device when the sealing structure is assembled with the material providing device and the material receiving device. At this time, the first sealing protrusion 5 surrounding the second opening 42 may also be provided on the second end face 2. The first sealing protrusion 5 is squeezed with the material end face of the inlet end of the material receiving device to produce elastic deformation.

[0070] In the embodiment of the present application, the sealing structure has a channel for conveying materials, and the channel passes through the two end faces of the body to form an opening, and the opening is used to communicate with the material end of the material device to form a material conveying passage, wherein a first sealing protrusion 5 is arranged around the opening, and the first sealing protrusion 5 abuts against the material end of the material device, and the first sealing protrusion 5 is squeezed with the material end face of the material end to produce elastic deformation, so as to achieve end face sealing, that is, the first sealing protrusion 5 is used to abut against the material end face of the material end of the material device and to squeeze with the material end face to produce elastic deformation; in this way, for the material conveying passage inside the equipment, the first sealing protrusion 5 on the sealing structure is used to perform end face sealing specifically for the channel for conveying materials, so as to improve the sealing effect. Furthermore, if there is a need for multi-channel material conveying, a surrounding sealing protrusion is arranged for the opening corresponding to each channel for conveying materials, and each channel for conveying materials is sealed, so as to effectively prevent leakage between the passages and achieve effective sealing.

[0071] Optionally, the first sealing protrusion 5 may be made of a soft material, specifically, silicone, fluororubber (FKM) rubber material, PET or other soft materials. The embodiment of the present application does not limit the material of the first sealing protrusion 5 .

[0072] Furthermore, from the perspective of product production efficiency, the material of the overall sealing structure can be designed to be the same as that of the first sealing protrusion 5, that is, the overall sealing structure can be integrally formed, so that the sealing structure provided in the embodiment of the present application can be produced in one go by making a suitable mold, thereby improving production efficiency.

[0073] In an optional embodiment, the first sealing protrusion 5 is arranged on the end surface in an inclined direction toward the opening, and a first inclined angle is formed between the first sealing protrusion 5 and the end surface. Figure 4 As shown in the angle A, there is an inclined angle between the first sealing protrusion 5 and the first end face 1, and the inclined direction of the first sealing protrusion 5 is toward the first opening 41. Figure 4 The scene shown is oriented horizontally.

[0074] In the embodiment of the present application, the first sealing protrusion 5 is arranged in an inclined manner, and the inclination direction is toward the first opening 41. In this way, when the first sealing protrusion 5 is squeezed and elastically deformed, it will present a deformation mode of contracting toward the first opening 41, which can improve the sealing effect at the first opening 41 and ensure that the material will not leak during the transportation process. Especially in the process of transmitting the material, when the material diffuses from the outlet to the end face, a force is generated to squeeze the first sealing protrusion 5, and the first sealing protrusion 5 produces elastic deformation by leveraging the force.

[0075] In an optional embodiment, the first sealing protrusion 5 includes a first top surface 51, a first bottom surface 52, a first side surface 53 and a second side surface 54; the first bottom surface 52 is connected to the end surface, the first top surface 51 is against the material end surface of the material end, the first side surface 53 is the side surface adjacent to the opening, and the second side surface 54 is the side surface away from the opening, as shown in detail. Figure 4 As shown, the first bottom surface 52 is connected to the first end surface 1, which can be specifically realized by the one-piece molding design described above. Optionally, the first top surface 51 can be parallel to the first bottom surface 52. The first top surface 51 is used to abut against the material end surface of the material supply device. The first top surface 51 and the first bottom surface 52 are designed to be parallel, which is conducive to the first sealing protrusion 5 being positively stressed. The first side surface 53 is the side of the first sealing protrusion 5 facing the first opening 41, which can be called the inner side surface, and the second side surface 54 is the side of the first sealing protrusion 5 facing away from the first opening 41, which can be called the outer side surface;

[0076] In an optional implementation, the first side surface 53 is a curved surface or a straight surface, and the second side surface 54 is a curved surface or a straight surface.

[0077] In one embodiment, the first side surface 53 is an arc surface that bends toward the first opening 41. The purpose of designing the inner side surface as an arc surface is to enable the first sealing protrusion 5 to present a deformation mode of contracting toward the first opening 41 when elastically deformed by being squeezed, thereby improving the sealing effect at the first opening 41 and ensuring that the material does not leak during the transportation process. In addition, the design of the arc surface can make the material diffuse to the end surface to the arc surface and when the arc surface is squeezed, the arc surface can play a buffering role. For example, some materials with a very fast flow rate have a relatively large impact force at the interface position and are very easy to leak. The arc surface design used in the embodiment of the present application can effectively buffer the impact force of the material at the interface position and ensure the sealing effect.

[0078] In an optional embodiment, the first inclination angle A is greater than or equal to 25° and less than 90°, that is, the inclination angle ranges from 25° to 90°. From the perspective of sealing effect, it can be further preferably greater than or equal to 30° and less than or equal to 60°, that is, the inclination angle ranges from 30° to 60°.

[0079] In an optional embodiment, when the first sealing protrusion 5 is squeezed against the material end surface at the material end to produce elastic deformation, the change of the first sealing protrusion 5 along the extrusion direction is greater than or equal to 0.1 cm and less than or equal to 0.5 cm, that is, the deformation range is 0.1 cm to 0.5 cm. From the perspective of sealing effect, it can be further preferably greater than or equal to 0.2 cm and less than or equal to 0.5 cm, that is, the deformation range is 0.1 cm to 0.5 cm.

[0080] It should be noted that the above-mentioned change refers to the change in size of the first sealing protrusion 5 along the extrusion direction when it is extruded. Figure 5 Take the scenario shown in as an example, Figure 5 The figure shows the scene after the sealing structure and the material device are assembled. Figure 5 In the scenario shown, the first sealing protrusion 5 is squeezed with the material end surface of the material device below, and the corresponding dimensional change along the extrusion direction is h1 marked in the figure, that is, the dimensional change in the vertical direction in the figure. It should be noted that in order to clearly show the deformation h1, Figure 5 The shape of the first sealing protrusion 5 is not deformed. It can be understood that in actual application scenarios, the shape of the first sealing protrusion 5 can be deformed due to extrusion, and the specific deformation amount is h1 shown in the figure.

[0081] In an optional implementation, a groove that cooperates with the first sealing protrusion 5 can be provided on the material end face of the material end. When the sealing structure is assembled with the material providing device and the material receiving device, part of the first sealing protrusion 5 is embedded in the groove on the end face of the material outlet end, thereby achieving a tight fit. It should be noted that in order to ensure the sealing effect, the first sealing protrusion 5 will also produce elastic deformation due to extrusion at this time. The specific deformation amount can be referred to the relevant description above.

[0082] It should be noted that one first sealing protrusion 5 may be provided around each first opening 41, or a plurality of first sealing protrusions 5 may be provided around each first opening 41. Multi-layer protection may further improve the sealing effect. Figures 1 to 4 The figure shows a scenario in which two first sealing protrusions 5 are provided, and the first opening 41 is circular. In this case, the first sealing protrusions 5 are provided around the first opening 41. The embodiment of the present application does not limit the number of first sealing protrusions 5 provided corresponding to each first opening 41. The specific structure of each first sealing protrusion 5 and the deformation amount during assembly can refer to the relevant description above, and will not be repeated here.

[0083] In an optional implementation, a cylinder 6 surrounding the first sealing protrusion 5 is provided on the end surface, and the material end enters the cylinder 6 and communicates with the channel 4.

[0084] See also Figures 6 to 9 A cylinder 6 surrounding the first sealing protrusion 5 is provided on the first end face 1, and the cylinder 6 is used to be sleeved on the outlet end of the material providing device when the sealing structure is assembled with the material providing device and the material receiving device; that is, the cylinder 6 is used as a jacket component of the outlet end of the material providing device in the actual application scenario, and is sleeved on the outlet end. It can be understood that the embodiment of the present application is explained by taking the case where the cylinder 6 is provided on the first end face 1 as an example. According to the same principle, the cylinder 6 can also be provided on the second end face 2. Correspondingly, the cylinder 6 provided on the second end face 2 is sleeved on the inlet end of the material receiving device. For specific structural details, please refer to the description of the case where the cylinder 6 is provided on the first end face 1 below.

[0085] The shape of the cylinder 6 depends on the outlet end of the material providing device and can be flexibly set according to the actual application scenario. It is understandable that in order not to affect the end face sealing effect of the first sealing protrusion 5, the cylinder 6 needs to be set around the first sealing protrusion 5. As described above, one or more channels 4 can be set on the sealing structure, and then correspond to one or more first sealing protrusions 5. In the embodiment of the present application, one or more cylinders 6 can also be set accordingly to meet the needs of one material conveying or multiple material conveying. Specifically, the number of cylinders 6 may not be exactly the same as the number of channels 4 and first sealing protrusions 5. For example, Figures 6 to 9A special scenario is shown, in which two channels 4 are used as a group for material transportation. Two first sealing protrusions 5 need to be provided as end face seals, while only one cylinder 6 can be provided.

[0086] A second sealing protrusion 7 is provided on the inner side surface of the cylinder 6. The second sealing protrusion 7 is used to abut against the outer side surface of the material end and squeeze the outer side surface of the material end to produce elastic deformation. Specifically, when the sealing structure is assembled with the material providing device and the material receiving device, the second sealing protrusion 7 squeezes the outer side surface of the material outlet end of the material providing device to produce elastic deformation. The second sealing protrusion 7 is provided on the inner side surface (or inner wall) of the cylinder 6, that is, the force generated by the assembly (specifically, the process of the cylinder 6 being sleeved on the outlet end of the material providing device) realizes the mutual squeezing of the side surface of the sealing structure and the outlet end of the material providing device, and then forms a tight fit through the elastic deformation of the second sealing protrusion 7, realizing a side seal, which works together with the end face seal realized by the first sealing protrusion 5 to realize double insurance and effectively improve the sealing effect.

[0087] In an optional embodiment, the second sealing protrusion 7 is obliquely arranged on the inner side surface of the cylinder 6, and a second oblique angle is formed between the second sealing protrusion 7 and the inner side surface of the cylinder 6, that is, there is an oblique angle between the second sealing protrusion 7 and the inner side surface of the cylinder 6.

[0088] When there are multiple second sealing protrusions 7, the inclination direction of the second sealing protrusions 7 satisfies any one of the following: the inclination direction of all the second sealing protrusions 7 is the same as the direction in which the material end enters the cylinder 6; the inclination direction of all the second sealing protrusions 7 is opposite to the direction in which the material end enters the cylinder 6; the inclination direction of a part of the second sealing protrusions 7 is the same as the direction in which the material end enters the cylinder 6, and the inclination direction of another part of the second sealing protrusions 7 is opposite to the direction in which the material end enters the cylinder 6.

[0089] Fig. 9 The diagram shows a scenario in which two second sealing protrusions 7 are provided, and the inclination direction of all the second sealing protrusions 7 is the same as the direction in which the outlet end of the material providing device is inserted into the cylinder 6, that is, the vertically upward direction in the diagram.

[0090] In the embodiment of the present application, there is an inclined angle between the second sealing protrusion 7 and the inner wall of the cylinder 6, so that the second sealing protrusion 7 can produce elastic deformation during assembly and extrusion, and form a tight fit with the side of the discharge end, so that the material providing device is tightly connected to the inner side of the cylinder 6. At the same time, when the material is transmitted, the leaked material diffuses to the inner side of the cylinder 6 of the second sealing protrusion 7 to the second sealing protrusion 7, squeezing the second sealing protrusion 7, so that the second sealing protrusion 7 is squeezed and deformed with the side of the discharge end, and fits more closely with the side of the discharge end to prevent material leakage.

[0091] In an optional embodiment, the second sealing protrusion 7 includes a second bottom surface 71, a third side surface 72 and a fourth side surface 73; the second bottom surface 71 is connected to the inner wall of the cylinder 6, which can be specifically realized by the one-piece molding design described above, and the direction of the third side surface 72 is opposite to the direction in which the outlet end of the material providing device is inserted into the cylinder, that is, Fig. 9 In the vertically downward direction, the fourth side surface 73 is oriented in the same direction as the direction in which the outlet end of the material providing device is inserted into the cylinder, that is, Fig. 9 The vertical upward direction;

[0092] In an optional implementation, the third side surface 72 is a curved surface or a straight surface, and the fourth side surface 73 is a curved surface or a straight surface.

[0093] In one embodiment, the third side surface 72 is an arc surface, and the bending direction is the same as the direction in which the outlet end of the material providing device is inserted into the cylinder 6, that is, Fig. 9 In the embodiment of the present application, the purpose of designing the third side surface 72 as an arc surface is that during the process of the material supply device's outlet end being inserted into the cylinder 6, the third side surface 72 that first contacts the outlet end realizes a transition effect through the arc surface design, while reducing a certain amount of insertion resistance, and gradually realizing the elastic deformation of the second sealing protrusion 7.

[0094] In one embodiment, the fourth side surface 73 is an arc surface, and the bending direction is opposite to the direction in which the outlet end of the material providing device is inserted into the cylinder 6. In the embodiment of the present application, the purpose of designing the fourth side surface 73 as an arc surface is: combined with the one-piece molding design method described above, there is a demoulding process after the sealing structure is formed. During the demoulding process, specifically inside the cylinder 6, it will be subjected to a force in the opposite direction to the fourth side surface 73. At this time, the transition effect is achieved by the arc surface design, which can reduce a certain demoulding resistance and thus improve production efficiency.

[0095] In an optional embodiment, the second inclination angle is greater than or equal to 25° and less than 90°, that is, the inclination angle ranges from 25° to 90°. From the perspective of sealing effect, it can be further preferred that the angle is greater than or equal to 30° and less than or equal to 60°, that is, the inclination angle ranges from 30° to 60°.

[0096] In an optional embodiment, when the second sealing protrusion 7 is squeezed against the outer side surface of the material end to produce elastic deformation, the change of the second sealing protrusion 7 along the extrusion direction is greater than or equal to 0.1 cm and less than or equal to 0.5 cm, that is, the deformation range is 0.1 cm to 0.5 cm. From the perspective of sealing effect, it can be further preferably greater than or equal to 0.2 cm and less than or equal to 0.5 cm, that is, the deformation range is 0.1 cm to 0.5 cm.

[0097] It should be noted that the above-mentioned height change refers to the dimensional change of the second sealing protrusion 7 along the extrusion direction when it is extruded. Fig.10 Take the scenario shown in as an example, Fig.10 The figure shows the scene after the sealing structure and the material device are assembled. Fig.10 In the scenario shown, the second sealing protrusion 7 is squeezed by the side of the outlet end below, and the corresponding dimensional change along the squeezing direction is h2 marked in the figure, that is, the dimensional change in the horizontal direction in the figure. It should be noted that in order to clearly show the deformation h2, Fig.10 The shape of the second sealing protrusion 7 is not deformed. It can be understood that in actual application scenarios, the shape of the second sealing protrusion 7 can be deformed due to extrusion, and the specific deformation amount is h2 shown in the figure.

[0098] In an optional implementation, a groove that cooperates with the second sealing protrusion 7 can be provided on the side of the discharge end. When the sealing structure is assembled with the material providing device and the material receiving device, part of the second sealing protrusion 7 is embedded in the groove on the end face of the discharge end, thereby achieving a tight fit. It should be noted that in order to ensure the sealing effect, the second sealing protrusion 7 will also produce elastic deformation due to extrusion at this time. The specific deformation amount can be referred to the relevant description above.

[0099] It should be noted that one or more second sealing protrusions 7 may be provided on the inner wall of the cylinder 6, and the multi-layer protection may further improve the sealing effect. Figures 6 to 9 The scenario of setting two second sealing protrusions 7 is shown in the figure. The embodiment of the present application does not limit the number of second sealing protrusions 7 corresponding to each cylinder 6. The specific structure of each second sealing protrusion 7 and the deformation amount during assembly can refer to the relevant description above and will not be repeated here.

[0100] Alternatively, if Fig. 9 As shown, a transition surface 60 can be provided on the inner wall of the cylinder 6. The transition surface 60 can be provided at the connection between the inner wall of the cylinder 6 and the first end surface 1 of the sealing structure. The transition surface 60 can be an inclined straight surface or an inclined arc surface, or a transition surface 60 composed of a top surface, a side surface and a bottom surface. The specific structure can be determined by the specific structure of the outlet end of the material providing device.

[0101] In an optional implementation, there are two openings on the end surface, and two support members 8 are also provided on the end surface. The connecting line between the two openings and the two lines between the two support members 8 are perpendicular to each other, so that the support member is positioned at 90° to the first sealing protrusion 5.

[0102] The two support members 8 are used to abut against the material end surface of the material end and squeeze the material end surface of the material end to generate elastic deformation.

[0103] like Figure 1 As shown, a support member 8 is provided on the first end face 1 of the sealing structure, and is used for the support member 8 to compress the material end face of the material supplying device and the material receiving device to produce elastic deformation when the sealing structure is assembled with the material supplying device and the material receiving device. An additional support member 8 is provided on the first end face 1, and its function is to ensure the accuracy of the relative position between the sealing structure and the material supplying device. The support member 8 is provided at a position 90° relative to the end face sealing protrusion, which can prevent the end face sealing protrusion from being skewed and making abnormal noises, and can also form an extrusion force on the end face of the material supplying device, so that the sealing structure and the end face of the material supplying device are closely matched. In addition, the resistance generated after the deformation can also improve the assembly stability.

[0104] Optionally, the support member 8 may be a rib, which can improve the assembly stability and the structural strength of the sealing structure.

[0105] In an optional embodiment, a blocking valve 43 is provided in the channel 4; Figures 13 to 15 As shown, the figure shows a scene in which three channels 4 are arranged in the sealing structure, and accordingly, a blocking valve 43 is arranged in each channel 4, that is, three blocking valves 43 are arranged. The conducting direction of the blocking valve 43 is the same as the material conveying direction.

[0106] In the embodiment of the present application, the function of the blocking valve 43 is to ensure that there will be no reverse leakage of the material during the transportation of the material in the channel 4. The blocking valve 43 has the characteristic of one-way conduction. By reasonably setting the relationship between the conduction direction of the blocking valve 43 and the direction of the material end, it is ensured that the blocking valve 43 is conductive along the material conveying direction and blocked in the reverse direction, thereby further improving the sealing effect.

[0107] The blocking valve 43 can be made of a soft material, specifically silicone, fluororubber (FKM) rubber material, PET and other soft materials. The embodiment of the present application does not limit the material of the blocking valve 43. Furthermore, from the perspective of product production efficiency, the material of the overall sealing structure can be designed to be the same as that of the blocking valve 43, that is, the overall sealing structure can be integrally formed, so that the sealing structure provided in the embodiment of the present application can be produced in one go by making a suitable mold, thereby improving production efficiency.

[0108] In an optional embodiment, the valve surface of the blocking valve 43 is provided with a plurality of cutouts 430, each of which is connected or intersected. Fig.15 Among the three blocking valves 43 shown in FIG. 1 , the middle blocking valve 43 has three cutouts 430 , which intersect with each other, and the blocking valves 43 on both sides have five cutouts 430 , which are connected with each other.

[0109] In the embodiment of the present application, providing multiple incisions 430 reduces resistance compared to a single incision, thereby avoiding affecting material conveying efficiency.

[0110] In a specific embodiment, the material providing device is a consumable container, and the material receiving device is an electric toothbrush. The consumable container and the electric toothbrush are detachably connected together, and a sealing structure is arranged at the outlet end of the consumable container and the inlet end of the electric toothbrush. A unidirectional conductive blocking valve whose conducting direction is the same as the consumable conveying direction is arranged in the channel of the sealing structure. The blocking valve can prevent the toothpaste in the consumable channel in the electric toothbrush from falling out when the consumable container (such as a toothpaste bottle) is removed from the electric toothbrush, which is more hygienic and does not affect the user's experience.
