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 is provided in the handle of the electric toothbrush, and the material receiving device is connected to a material providing device which is a material container, that is, after the handle of the electric toothbrush is fixedly connected to the material container (for example, a toothpaste bottle), the material transmission channels of the material receiving device and the material providing device are connected, and the input end of the electric toothbrush receives the toothpaste transmitted from the toothpaste bottle; or, the handle of the electric toothbrush is provided with a material receiving device and a material providing device, for example, the material providing device is the pump as exemplified above, and the material providing 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 handle of the electric toothbrush is provided with a material providing device, and the brush head of the electric toothbrush is provided with a material receiving device, for example, the material providing device is a hollow motor shaft, and the material receiving device is the input end of the material channel of the brush head handle.

[0062] The material receiving device has an inlet end, which refers to the end for receiving the material. The material end can be the outlet end of the material providing device, or the 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 Figure 1 , 2 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 technology, including:

[0065] The main body comprises a top wall 1, a bottom wall 2 and a side wall 3, wherein the top wall 1 and the bottom wall 2 are connected with the side wall 3 to form a cylinder 5;

[0066] The body is provided with one or more channels 4 for conveying materials. The channel 4 penetrates the top wall 1 to form a first opening 41, and the channel 4 penetrates the bottom wall 2 to form a second opening 42. The top wall 1 is in the same direction as the material conveying direction, and the bottom wall 2 is in the opposite direction to the material conveying direction; that is, the first opening 41 can be called the outlet of the channel 4, and the second opening 42 can be called the inlet of the channel 4; it can be understood that based on the actual material conveying needs, one or more channels 4 can be provided to meet the needs of conveying one material or multiple materials. For example Figure 1 , 2 Shown in FIG. 1 is a scene with three channels.

[0067] The outlet end of the material providing device enters the channel 4 from the second opening 42, and the outlet end is connected with the inlet end of the material receiving device. Optionally, the inlet end may enter the channel 4 from the first opening 41 and be connected with the outlet end, or the inlet end may not enter the first opening 41, but be directly connected with the outlet end at the first opening 41, or the inlet end may be connected with the outlet end at the first opening 41 through, for example, a conduit.

[0068] The cylinder 5 formed by the top wall 1 and the bottom wall 2 connected with the side wall 3 is used to be mounted on the discharge 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 5 is used as the outer sleeve component of the discharge end of the material providing device in the actual application scenario, and is mounted on the discharge end; the shape of the cylinder 5 can be cylindrical or square cylindrical, depending on the shape of the discharge end of the material providing device, and can be flexibly set according to the actual application scenario.

[0069] A first sealing protrusion 6 is provided on the inner side surface of the side wall 3, and is used for the first sealing protrusion 6 to abut against the outer side surface of the outlet end of the material providing device entering the channel 4 from the second opening 42 when the sealing structure is assembled with the material providing device and the material receiving device, and the first sealing protrusion 6 is squeezed with the outer side surface of the outlet end to produce elastic deformation.

[0070] When the cylinder 5 is cylindrical, the first sealing protrusion 6 forms an annular protrusion on the inner side surface of the side wall 3 of the cylinder 5. When the cylinder 5 is square cylindrical, the first sealing protrusion 6 forms a square protrusion on the inner side surface of the side wall 3 of the cylinder 5, depending on the shape of the cylinder 5.

[0071] In the embodiment of the present application, the sealing structure has a channel 4 for conveying materials, the channel 4 penetrates the top wall 1 of the sealing structure to form a first opening 41, the channel 4 penetrates the top wall 1 of the sealing structure to form a second opening 42, the material outlet end of the material providing device enters the channel 4 from the second opening 42, the material outlet end is connected to the material inlet end of the material receiving device, and constitutes a material conveying passage of the material outlet end-channel-material inlet end of the material receiving device, wherein the top wall 1 and the bottom wall 2 are connected with the side wall 3 to form a cylinder 5 surrounding the first opening 41, and a first sealing protrusion 6 is provided on the inner side of the cylinder 5, and the first sealing protrusion 6 is squeezed with the outer side surface of the discharge end to produce elastic deformation, thereby achieving side sealing; when the material of the material providing device is transmitted from the discharge end to the inlet end of the material receiving device through the discharge end, if there is leakage of material, it will spread from the discharge end to the outer side surface of the discharge end and be squeezed with the first sealing protrusion 6. On the one hand, the first sealing protrusion 6 is squeezed with the leaking material to produce elastic deformation and be tightly connected with the outer side surface of the discharge end, and on the other hand, it blocks material leakage and plays a sealing role; in this way, for the material conveying passage inside the equipment, the side sealing can be improved by the first sealing protrusion 6 on the inner side surface of the cylinder 5. Furthermore, if there is a need for multi-channel material conveying, multiple cylinders 5 with first sealing protrusions 6 on the inner side surface can be set for the openings corresponding to the multiple material conveying channels, and each material conveying channel is sealed to effectively prevent leakage between the channels and achieve effective sealing.

[0072] Optionally, the first sealing protrusion 6 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 6 .

[0073] 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 6, 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.

[0074] In an optional embodiment, the first sealing protrusion 6 is obliquely arranged on the inner side surface of the side wall 3 , and a first oblique angle is formed between the first sealing protrusion 6 and the inner side surface of the side wall 3 , that is, there is an oblique angle between the first sealing protrusion 6 and the inner side surface of the side wall 3 .

[0075] When there are multiple first sealing protrusions 6, the inclination direction of the first sealing protrusions satisfies any one of the following: the inclination direction of all the first sealing protrusions 6 is the same as the direction in which the outlet enters the channel 4; the inclination direction of all the first sealing protrusions 6 is opposite to the direction in which the outlet enters the channel 4; the inclination direction of a part of the first sealing protrusions 6 is the same as the direction in which the outlet enters the channel 4, and the inclination direction of another part of the first sealing protrusions 6 is opposite to the direction in which the outlet enters the channel 4.

[0076] Figure 2 What is shown is a scenario where the inclination direction of the first sealing protrusion 6 is the same as the direction in which the outlet end of the material providing device enters the channel 4 (ie, is inserted into the cylinder 5), that is, the vertically upward direction in the figure.

[0077] In the embodiment of the present application, an inclined angle is provided between the first sealing protrusion 6 and the inner side surface of the side wall 3 of the cylinder 5, so that the first sealing protrusion 6 can produce elastic deformation during assembly and extrusion, and form a close fit with the outer side surface of the outlet end.

[0078] In an optional embodiment, the first sealing protrusion 6 includes a first bottom surface 61, a first side surface 62 and a second side surface 63; the first bottom surface 61 is connected to the inner side surface of the side wall 3, which can be specifically realized by the one-piece molding design described above, and the direction of the first side surface 62 is opposite to the direction in which the outlet end of the material providing device enters the channel 4 (i.e., inserts into the cylinder 5), that is, Figure 2 In the vertically downward direction, the second side surface 63 is oriented in the same direction as the direction in which the outlet end of the material supply device enters the channel 4 (i.e., is inserted into the cylinder 5), that is, Figure 2 In the vertical upward direction.

[0079] In an optional implementation, the first side surface 62 is a curved surface or a straight surface, and the second side surface 63 is a curved surface or a straight surface.

[0080] In one embodiment, the first side surface 62 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 5, that is, Figure 2 In the vertical upward direction.

[0081] In the embodiment of the present application, the purpose of designing the first side surface 62 as a curved surface is that during the process of the material supply device's discharge end being inserted into the cylinder 5, the first side surface 62 that first contacts the discharge end achieves a transition effect through the curved surface design, thereby gradually achieving elastic deformation of the first sealing protrusion 6 while reducing a certain insertion resistance.

[0082] In one embodiment, the second side surface 63 is an arc surface, and the bending direction is opposite to the direction in which the outlet end of the material providing device enters the channel 4 (ie, is inserted into the cylinder 5).

[0083] In the embodiment of the present application, the purpose of designing the second side surface 63 as a curved surface is: combined with the one-piece molding design method described above, there is a demolding process after the sealing structure is formed. During the demolding process, specifically inside the cylinder 5, it will be subjected to a force in the opposite direction to the second side surface 63. At this time, the transition effect is achieved through the curved surface design, which can reduce a certain degree of demolding resistance and thereby improve production efficiency.

[0084] In an optional embodiment, the first 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°.

[0085] In an optional embodiment, when the first sealing protrusion 6 is squeezed against the outer side surface of the outlet end of the material providing device to produce elastic deformation, the change of the first sealing protrusion 6 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.

[0086] It should be noted that the above-mentioned change refers to the dimensional change of the first sealing protrusion 6 along the extrusion direction when it is extruded. Figure 3 Take the scenario shown in as an example, Figure 3 The figure shows the scene after the sealing structure and the material device are assembled. Figure 3 In the scenario shown, the first sealing protrusion 6 is squeezed by the side of the outlet below, and the corresponding dimensional change along the squeezing direction is h1 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 h1, Figure 3 The shape of the first sealing protrusion 6 is not deformed. It can be understood that in actual application scenarios, the shape of the first sealing protrusion 6 can be deformed due to extrusion, and the specific deformation amount is h1 shown in the figure.

[0087] In an optional implementation, a groove that cooperates with the first sealing protrusion 6 can be provided on the outer surface of the discharge end. When the sealing structure is assembled with the material providing device and the material receiving device, part of the first sealing protrusion 6 is embedded in the groove on the end surface of the discharge end, thereby achieving a tight fit. It should be noted that in order to ensure the sealing effect, the first sealing protrusion 6 will also produce elastic deformation due to extrusion at this time. The specific deformation amount can be referred to the relevant description above.

[0088] It should be noted that one first sealing protrusion 6 may be provided on the inner side of the side wall 3, or a plurality of first sealing protrusions 6 may be provided. The multi-layer protection may further improve the sealing effect. Figure 1 , 2 The scenario of setting two first sealing protrusions 6 is shown in the figure. The embodiment of the present application does not limit the number of first sealing protrusions 6 corresponding to each cylinder 5. The specific structure of each first sealing protrusion 6 and the deformation amount during assembly can refer to the relevant description above and will not be repeated here.

[0089] Alternatively, if Figure 2 As shown, a transition surface 50 is provided on the inner side surface of the side wall 3, corresponding to the position where the port at the inlet end of the material receiving device is connected to the port at the outlet end; the transition surface 50 is an arc surface or a straight surface, that is, the transition surface 50 can be an inclined straight surface or an inclined arc surface, or a transition surface composed of a top surface, a side surface and a bottom surface; it can be specifically determined by the specific structure of the outlet end of the material providing device.

[0090] In an alternative embodiment, Figures 4 to 7 As shown, the top wall 1 includes a first end face 11 and a second end face 12, the first end face 11 is the end face facing away from the second opening 42, and the second end face 12 is the end face facing the second opening 42, the channel 4 penetrates the first end face 11 to form a first opening 41, and the channel 4 penetrates the second end face to form a third opening 43; a second sealing protrusion 7 is arranged on the second end face 12 to surround the third opening 43; the second sealing protrusion 7 is abutted against the end face of the discharge end, and the second sealing protrusion 7 is squeezed with the end face of the discharge end to produce elastic deformation.

[0091] In an alternative embodiment, see Figure 2 , Figure 7 In one embodiment, Figure 2 As shown, a baffle 30 is provided on the inner side surface of the side wall 3, and the baffle 30 includes a first end surface 11 and a second end surface 12, the first end surface 11 is the end surface facing away from the second opening 42, and the second end surface 12 is the end surface facing the second opening 42; the channel 4 penetrates the second end surface 12 to form a third opening 43, and the channel 4 penetrates the first end surface 11 to form a fourth opening 44; the second end surface 12 is provided with a second sealing protrusion 7 surrounding the third opening 43; the second sealing protrusion 7 is abutted against the end surface of the outlet end, and the second sealing protrusion 7 is squeezed with the end surface of the outlet end to produce elastic deformation. It should be noted that if the first end surface 11 of the baffle 30 is coplanar with the outer end surface of the top wall (that is, the same surface), as shown in FIG. Figure 6 and Figure 7As shown, the channel 4 passes through the first end face 11 to form a fourth opening 44, and the fourth opening 44 is also the first opening 41 at this time. The channel 4 passes through the second end face 12 to form a third opening 43. In addition, the inlet end of the material receiving device can enter the channel 4 from the first opening 41 and abut against the first end face 11 of the baffle, and communicate with the outlet end of the material providing device. At this time, a third sealing protrusion (not shown in the figure) can also be provided on the first end face 11. The third sealing protrusion surrounds the fourth opening 44 and is inclined toward the fourth opening 44, forming an inclined angle with the first end face 11. The third sealing protrusion abuts against the end face of the inlet end, and the third sealing protrusion is squeezed with the end face of the inlet end to produce elastic deformation; and the structure of the third sealing protrusion can be the same as or different from the structure of the second sealing protrusion 7, and the inclination angle formed by it and the first end face is in the range of 25° to 90°. In order to further improve the sealing effect, the inclination angle can further be in the range of 30° to 60°. It is understandable that the sealing protrusion can be provided on both the first end face 11 and the second end face 12, or on either one of the first end face 11 and the second end face 12 to achieve end face sealing. When the sealing protrusions are provided at the same time, a double sealing effect can be achieved.

[0092] In the embodiment of the present application, a second sealing protrusion 7 surrounding the third opening 43 is provided on the second end face 12. It can be understood that in order not to affect the side sealing effect of the first sealing protrusion 6 and also to enable the second sealing protrusion 7 to play a sealing role, the second sealing protrusion 7 needs to be arranged inside the cylinder 5.

[0093] The second sealing protrusion 7 is used to produce elastic deformation by squeezing the end surface of the material supply end of the material supply device when the sealing structure is assembled with the material supply device and the material receiving device. That is, the sealing structure and the end surface of the material supply end of the material supply device are squeezed against each other by the force generated by the assembly, and then a tight fit is formed by the elastic deformation of the second sealing protrusion 7 to achieve an end surface seal, which works together with the side seal achieved by the first sealing protrusion 6 to achieve double insurance and effectively improve the sealing effect.

[0094] Furthermore, it should be noted that Figure 2 In the scenario shown, the second sealing protrusion 7 is specifically arranged on the end surface of the baffle 30 inside the cylinder 5, for Figure 4-7 In the illustrated scenario, the second sealing protrusion 7 is specifically arranged on the end surface of the top wall 1 .

[0095] Regarding the above Figure 2 , Figure 4 In order to uniformly describe the structure of the second sealing protrusion 7, the following is provided: Figure 6 In this figure, some other structures are omitted, and the structural details of the second sealing protrusion 7 are highlighted.

[0096] In an optional embodiment, see Figure 7 , Figure 7 is a specific cross-sectional view of the second sealing protrusion 7 corresponding to the third opening 43, as shown Figure 7 The second sealing protrusion 7 is tilted on the second end face 12 toward the third opening 43, and a second tilt angle is formed between the second sealing protrusion 7 and the second end face 12, that is, there is a tilt angle between the second sealing protrusion 7 and the first end face 1, and the tilt direction of the second sealing protrusion 7 is toward the first opening 41. Figure 7 The scene shown is oriented horizontally.

[0097] In an optional implementation, the second sealing protrusion 7 includes a first top surface 71 , a second bottom surface 72 , a third side surface 73 and a fourth side surface 74 .

[0098] The second bottom surface 72 is connected to the second end surface 12, the first top surface 71 is abutted against the end surface of the outlet end, the third side surface 73 is the side surface adjacent to the third opening 43, and the fourth side surface 74 is the side surface away from the third opening 43. The third side surface 73 and the fourth side surface 74 are connected to the first top surface 71, which can be specifically achieved through the one-piece molding design described above. Optionally, the first top surface 71 can be parallel to the second bottom surface 72, and the first top surface 71 is used to abut against the end surface of the outlet end of the material providing device. The first top surface 71 and the second bottom surface 72 are designed to be in a parallel relationship, which is beneficial to the second sealing protrusion 7 to be subjected to positive force. The third side surface 73 is the side surface of the second sealing protrusion 7 facing the first opening 41, which can be called the inner side surface, and the fourth side surface 74 is the side surface of the second sealing protrusion 7 facing away from the first opening 41, which can be called the outer side surface.

[0099] In an optional implementation, the third side surface 73 is a curved surface or a straight surface, and the fourth side surface 74 is a curved surface or a straight surface.

[0100] In one embodiment, the third side surface 73 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 realize that the second sealing protrusion 7 can present a deformation mode of contraction toward the first opening 41 when elastically deformed by being squeezed, which can improve the sealing effect at the first opening 41 and ensure that the material will not leak during the transportation process. In addition, the design of the arc surface can buffer the material on the surface. 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.

[0101] In one 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 preferably 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°.

[0102] In an optional embodiment, when the second sealing protrusion 7 is squeezed against the end face of the material outlet end of the material providing device to produce elastic deformation, the change of the second sealing protrusion 7 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.

[0103] It should be noted that the above-mentioned change refers to the dimensional change of the first sealing protrusion 6 along the extrusion direction when it is extruded. Figure 7 Take the scene shown in as an example, which is the size change in the vertical direction in the figure.

[0104] In an optional implementation, a groove that cooperates with the second sealing protrusion 7 can be provided on the end face 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.

[0105] It should be noted that one second sealing protrusion 7 may be provided around each first opening 41, or a plurality of second sealing protrusions 7 may be provided around each first opening 41. Multi-layer protection may further improve the sealing effect. Figure 7 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 set corresponding to each first opening 41. 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.

[0106] In an optional embodiment, a blocking valve 40 is provided in the channel 4; Figures 9 to 11 As shown, the figure shows a scene in which three channels 4 are arranged in the sealing structure. Accordingly, a blocking valve 40 is arranged in each channel 4, that is, three blocking valves 40 are arranged.

[0107] The conducting direction of the blocking valve 40 is the same as the conveying direction of the material. Specifically, the conducting direction of the blocking valve 40 is the same as the direction of the outlet of the material providing device, and the conducting direction of the blocking valve 40 is opposite to the direction of the inlet of the material receiving device.

[0108] In the embodiment of the present application, the function of the blocking valve 40 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 40 has the characteristic of one-way conduction. By reasonably setting the relationship between the conduction direction of the blocking valve 40 and the direction of the material end, it is ensured that the blocking valve 40 is conductive along the material conveying direction and blocked in the reverse direction. On the one hand, this can avoid material residue, and on the other hand, it can further improve the sealing effect.

[0109] The blocking valve 40 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 40. 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 40, 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.

[0110] In an optional embodiment, the valve surface of the blocking valve 40 is provided with a plurality of cutouts 401, and each of the cutouts 401 is connected or intersected. Fig.11 Among the three blocking valves 40 shown in the figure, the middle blocking valve 40 has three cutouts 401, each of which crosses each other, and the blocking valves 40 on both sides have five cutouts 401, each of which is connected to each other.

[0111] In the embodiment of the present application, multiple incisions 401 are provided to reduce resistance compared to a single incision, thereby avoiding affecting the material conveying efficiency.

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.
