Description

Technical Field

[0001] This utility model relates to the field of razors, and further to a housing structure and a razor. Background Technology

[0002] Currently, most shavers use a split shell design, with the mounting bracket fixed inside the shell, and the upper and lower shells connected by screws. This design has several drawbacks. First, the screws and mounting holes are exposed, usually requiring an additional outer shell for aesthetic purposes. This not only increases production costs but also complicates the assembly process, extends production time, and further increases costs. Second, the extra outer shell increases the product's size, reducing portability. Furthermore, some shavers use snap-fit ​​connections between the upper and lower shells to conceal the connection, but this method lacks sufficient strength and easily leaves noticeable gaps or marks, affecting the overall aesthetics of the product. Moreover, under frequent disassembly and assembly or under significant stress, the snap-fit ​​is prone to deformation or damage, leading to connection failure. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a shell structure and a shaver that snaps together a third body with a second body inside a first body. Simultaneously, the outer walls of the first and third bodies are fitted together, concealing the snap-fit ​​connection structure within the first body. This avoids exposed snap-fit ​​structures or gaps affecting the appearance, resulting in a cleaner and more aesthetically pleasing product surface. The second body, serving as the mounting carrier for the transmission components, possesses high structural strength, distributing the connection force between the third and first bodies to the second body, thereby improving the overall stability and reliability of the connection, while also effectively controlling the product's size.

[0004] To achieve the above objectives, this utility model provides a housing structure, including a first body, a second body, and a third body, wherein the top of the first body is adapted to be provided with a cutter head assembly;

[0005] The second body is fixedly disposed inside the first body, and a transmission component is adapted to be disposed on the second body. The transmission component is adapted to drive and connect the cutter head assembly after passing through the first body.

[0013] The second body is provided with a second mounting groove on the side away from the circuit board. The second mounting groove is adapted to accommodate a driving component, which is adapted to pass through the second body and then drively connect to the transmission assembly.

[0014] In some embodiments, the first body is further provided with a first through hole, and the fourth body is further provided with a second through hole. The first through hole and the second through hole are also adapted to be provided with a button assembly, which is connected to a contact on a circuit board.

[0015] In some embodiments, a fifth body is also included, which is fixedly disposed on the top of the first body. The cutter head assembly is detachably mounted on the top of the fifth body. A first seal is also provided between the top of the first body and the bottom of the fifth body, and the transmission assembly is adapted to pass through the first seal.

[0016] According to another aspect of this application, a razor is further provided, including any of the housing structures of the above preferred embodiments.

[0017] Compared with the prior art, the housing structure and razor provided by this utility model have at least one of the following beneficial effects:

[0018] 1. The third body is snapped together with the second body inside the first body, while the outer walls of the first and third bodies fit together. The snap-fit ​​connection structure is hidden inside the first body, avoiding exposed snap-fit ​​structures or gaps that would affect the appearance, thus making the product surface cleaner and more aesthetically pleasing. The second body, as the mounting carrier of the transmission component, has high structural strength and can distribute the connection force between the third body and the first body to the second body, thereby improving the stability and reliability of the overall connection, while also effectively controlling the product's size.

[0019] 2. Since the battery assembly is fixed between the second and third bodies, integrating the battery assembly and the snap-fit ​​connection structure into the same area not only optimizes the utilization efficiency of the internal space, but also reduces the complexity caused by additional fixing structures.

[0020] 3. By cleverly fixing the charging component between the abutment and the card plate, the installation method of the charging component is not only optimized, ensuring the rapid positioning and stable installation of the charging component during the assembly process, so that it will not loosen due to external force or vibration during use, but also reducing the need for additional fixing structures, thus reducing production costs and assembly complexity.

[0021] 4. The fourth body is located on one side of the first body and is fixed to the first body and the third body by means of a snap-fit ​​connection. This not only further enhances the connection strength between the first body and the third body, but also distributes the connection force to a wider area through the auxiliary support of the fourth body, thereby effectively improving the stability and reliability of the entire shell structure.

[0022] 5. The battery assembly is located at the bottom of the drive unit and the circuit board, and is positioned between the drive unit and the circuit board. This cleverly utilizes the lower space of the second body, avoiding an increase in product size due to additional space occupation. This makes the entire shaver housing lighter, more compact, and easier to carry and use. Attached Figure Description

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.

[0043] refer to Figures 1 to 3 This utility model provides a housing structure, including a first body 1, a second body 2 and a third body 3. The top of the first body 1 is adapted to be provided with a cutter head assembly 50. The second body 2 is fixedly disposed inside the first body 1, and a transmission assembly 20 is adapted to be disposed on the second body 2. The transmission assembly 20 is adapted to pass through the first body 1 and drive and connect to the cutter head assembly 50. The third body 3 is snapped below the second body 2 and the outer walls of the first body 1 and the third body 3 are fitted together.

[0044] In this embodiment, the third body 3 is snapped together with the second body 2 inside the first body 1, and the outer walls of the first body 1 and the third body 3 are fitted together. The snap-connection structure is hidden inside the first body 1, avoiding the appearance of the exposed snap-connection structure or gaps, thus making the product surface cleaner and more beautiful. The second body 2, as the mounting carrier of the transmission component 20, has high structural strength and can distribute the connection force between the third body 3 and the first body 1 to the second body 2, thereby improving the stability and reliability of the overall connection, while also effectively controlling the size of the product.

[0045] Specifically, this application aims to improve the aesthetics, stability, and portability of the product, while optimizing the assembly process and production costs. The housing structure includes a first body 1, a second body 2, and a third body 3. The first body 1 serves as the main structure, with its top suitable for mounting the blade assembly 50, providing stable support and precise positioning for the blade assembly 50. The second body 2 is fixedly disposed inside the first body 1, and is suitable for mounting a transmission assembly 20. This transmission assembly 20 can penetrate the first body 1 and achieve a transmission connection with the blade assembly 50, ensuring the efficient operation of the shaver's core functions. The third body 3 is disposed below the second body 2 via a snap-fit ​​mechanism, and the outer walls of the first body 1 and the third body 3 are fitted together, so that the snap-fit ​​connection structure is completely hidden inside the first body 1, effectively avoiding the impact of exposed snaps or gaps on the product's appearance, thus making the product surface cleaner and more aesthetically pleasing. The second body 2, serving as the mounting carrier for the transmission component 20, not only bears the core transmission function of the shaver but also, due to its high structural strength, disperses the connection force between the third body 3 and the first body 1, thereby improving the overall stability and reliability of the connection. Simultaneously, through optimized structural layout, this design effectively controls the product's size without adding unnecessary outer casing, maintaining good portability while meeting functional requirements. Furthermore, the concealed snap-fit ​​connection method not only enhances the product's aesthetics but also reduces the assembly complexity and production costs associated with traditional exposed connection methods, further improving the product's market competitiveness.

[0046] More specifically, the second body 2 has several locking plates 28 at its bottom, and the third body 3 has several hooks 34 inside, which are suitable for snapping onto the locking plates 28. During assembly, the third body 3 is precisely snapped onto the locking plates 28 at the bottom of the second body 2 through its internal hooks 34. This not only has a simple structure and convenient operation, but also achieves a fast and stable assembly effect. The snap-fit ​​connection between the locking plates 28 and the hooks 34 ensures that it can withstand certain external forces and frequent disassembly and assembly operations during normal use, thereby effectively improving the stability and reliability of the overall structure. At the same time, the high precision of the fit between the locking plates 28 and the hooks 34 ensures that the outer walls of the first body 1 and the third body 3 fit tightly together, further concealing the connection structure and making the product appearance cleaner and more aesthetically pleasing. Several beveled surfaces for snapping are provided at the edges of the locking plates 28, and corresponding beveled surfaces for snapping are also provided on the hooks 34. The specific structure of these bevels is not further limited here, as it is something that those skilled in the art can conceive of.

[0047] Furthermore, the inner wall of the first body 1 is provided with several first fixing posts 11, and the left and right sides of the second body 2 are provided with several second fixing posts 21. The first fixing posts 11 and the second fixing posts 21 are adapted to be fixedly connected by locking components. During assembly, the first fixing posts 11 and the second fixing posts 21 are fixedly connected by locking components (such as screws or rivets), thereby achieving a stable connection between the first body 1 and the second body 2. This not only ensures a tight connection between the two, but also effectively disperses the stress generated by the transmission component 20 during operation, further improving the stability and reliability of the overall structure. The top of the first body 1 is also provided with several first limiting posts 12, and the top of the second body 2 is also provided with several second limiting posts 22. The second limiting posts 22 are provided with second limiting grooves, and the first limiting posts 12 are adapted to be inserted into the second limiting grooves of the second limiting posts 22. During assembly, the first limiting posts 12 are adapted to be inserted into the second limiting grooves of the second limiting posts 22, forming a precise limiting fit. On the one hand, it ensures the correct position of the second body 2 inside the first body 1, avoiding displacement caused by assembly errors or external forces. On the other hand, the tight fit between the first limiting post 12 and the second limiting groove further enhances the connection strength between the first body 1 and the second body 2, while providing a stable support foundation for the installation and operation of the transmission assembly 20. The first fixing post 11 and the first limiting post 12 also effectively prevent structural loosening caused by long-term use or frequent disassembly, thereby extending the product's service life and improving the user experience.

[0048] Further, refer to Figure 3 and Figure 4 The second body 2 has a first battery slot 23 on the bottom plate 28, and the third body 3 has a second battery slot 31 inside. The second battery slot 31 is located inside a number of hooks 34. The first battery slot 23 and the second battery slot 31 are suitable for snapping and fixing the battery assembly 24.

[0049] In this embodiment, since the battery assembly 24 is fixed between the second body 2 and the third body 3, the battery assembly 24 and the snap-fit ​​connection structure are integrated in the same area, which not only optimizes the utilization efficiency of the internal space, but also reduces the complexity caused by the additional fixing structure.

[0050] Specifically, the second body 2 has a first battery slot 23 on the bottom plate 28, which is located inside the plate 28. The third body 3 has a second battery slot 31, which is located inside several hooks 34. During assembly, the battery assembly 24 is precisely snapped and fixed between the first battery slot 23 and the second battery slot 31, forming a stable fitting structure. This not only provides a reliable installation position for the battery assembly 24, but also ensures that the battery assembly 24 will not loosen or shift due to vibration or external force during use through the tight fit between the first battery slot 23 and the second battery slot 31. Through the limiting effect of the first battery slot 23 and the second battery slot 31, the battery assembly 24 can be quickly positioned during assembly, further improving production efficiency. First, by embedding the battery assembly 24 between the plate 28 of the second body 2 and the hooks 34 of the third body 3, the space occupied by the snap-fit ​​connection structure is fully utilized, avoiding additional fixing structures and wasted space, thereby significantly improving the utilization efficiency of the internal space and reducing the overall height of the first body 1 and the third body 3. This not only reduces the number and complexity of parts, but also lowers production costs and assembly difficulty. Secondly, integrating the battery assembly 24 with the snap-fit ​​connection structure in the same area makes the installation and removal of the battery assembly 24 more convenient. When replacing the battery, users do not need to disassemble the entire housing; they can quickly replace the battery using a simple snap-fit ​​operation, improving the user experience. At the same time, this also ensures the stability of the battery assembly 24 during use; even under frequent vibrations or external impacts, the battery assembly 24 remains stable and will not loosen or shift. This also brings greater compactness and consistency to the overall product structure. By combining the battery assembly 24 with the snap-fit ​​connection structure area, the visual abruptness or structural looseness caused by additional fixing structures is avoided, making the entire shaver housing more compact, aesthetically pleasing, and with a stronger sense of unity. This also provides more space for the transmission assembly 20 and other internal components, further optimizing the internal layout of the product and improving its overall performance and reliability.

[0051] Further, refer to Figure 4 The third body 3 is provided with a charging channel 32, and a charging component 320 is suitable for being installed in the charging channel 32. An abutment part 321 is provided on the inner side wall of the charging channel 32. The charging component 320 is disposed through the charging channel 32 and abuts and is fixed between the abutment part 321 and the card plate 28.

[0052] In this embodiment, by cleverly fixing the charging component 320 between the abutment portion 321 and the retaining plate 28, not only is the installation method of the charging component 320 optimized, ensuring the rapid positioning and stable installation of the charging component 320 during the assembly process, so that it will not loosen due to external force or vibration during use, but also the need for additional fixing structures is reduced, thereby reducing production costs and assembly complexity.

[0053] Specifically, the charging component 320 is disposed through the charging channel 32 and tightly engages with the abutment portion 321 within the charging channel 32 through its outer structure. Simultaneously, it abuts and is fixed between the abutment portion 321 and the retaining plate 28 at the bottom of the second body 2. This allows the charging component 320 to be quickly positioned and securely installed during assembly, further enhancing its stability and preventing it from loosening due to external forces or vibrations during use. By cleverly fixing the charging component 320 between the abutment portion 321 and the retaining plate 28, not only is the installation method of the charging component 320 optimized, but the need for additional fixing structures is also reduced, lowering production costs and assembly complexity. At the same time, this provides greater flexibility for the internal space layout of the shaver, ensuring a reasonable arrangement of the battery assembly 24, transmission assembly 20, and other internal components, further improving the overall performance and user experience of the product.

[0054] Further, refer to Figure 7 and Figure 8 It also includes a fourth body 4, which is disposed on one side of the first body 1 and is adapted to snap-fit ​​connection between the first body 1 and the third body 3.

[0055] In this embodiment, the fourth body 4 is disposed on one side of the first body 1 and is fixed to the first body 1 and the third body 3 by means of a snap-fit ​​connection. This not only further enhances the connection strength between the first body 1 and the third body 3, but also disperses the connection force to a wider area through the auxiliary support of the fourth body 4, thereby effectively improving the stability and reliability of the entire shell structure.

[0056] Specifically, the fourth body 4 is tightly connected to the first body 1 and the third body 3 via snap-fit ​​connections, forming a stable triangular support structure. During production, workers can quickly assemble the fourth body 4 with the first body 1 and the third body 3, reducing assembly time and improving production efficiency. This structure effectively disperses the connecting force between the first body 1 and the third body 3, preventing structural loosening or damage caused by localized stress concentration, thereby significantly improving the overall connection strength and stability. With the auxiliary support of the fourth body 4, the impact resistance and deformation resistance of the entire shell structure are significantly improved. This allows the shaver to better withstand accidental drops or collisions during daily use, extending the product's lifespan and reducing repair or replacement costs due to structural damage. More specifically, the outer wall of the second body 2 is provided with a plurality of first snap-fit ​​portions 15, each with a first snap-fit ​​groove; the outer wall of the third body 3 is provided with a plurality of second snap-fit ​​portions 33, each with a second snap-fit ​​groove; and the fourth body 4 is provided with a plurality of third snap-fit ​​portions 41, which are adapted to snap-fit ​​connect the first snap-fit ​​portions 15 and the second snap-fit ​​portions 33. The first snap-fit ​​portions 15 and the second snap-fit ​​portions 33 are respectively located on the outer walls of the second body 2 and the third body 3, providing precise connection points for the third snap-fit ​​portions 41 of the fourth body 4. When the third snap-fit ​​portion 41 of the fourth body 4 is inserted into the first snap-fit ​​groove of the first snap-fit ​​portion 15 and the second snap-fit ​​groove of the second snap-fit ​​portion 33, a quick and stable connection can be achieved. This snap-fit ​​connection method is not only simple to operate but also effectively disperses the connection force, avoiding local stress concentration, thereby improving the impact resistance and durability of the overall structure.

[0057] It is worth noting that the fourth body 4 not only considers the functional requirements of connection strength but also takes into account the product's appearance design. The fourth body 4 can be used as a display panel. Through its ingenious shape and close fit with the first body 1 and the third body 3, the fourth body 4 can be integrated with the overall shell, further enhancing the product's overall look and aesthetics, making it more competitive in the market while meeting functional requirements.

[0058] Further, refer to Figure 5 and Figure 6 The second body 2 is provided with a first mounting groove 25 on the side near the fourth body 4. The opening of the first mounting groove 25 is also provided with a number of fixing parts 251. The first mounting groove 25 is suitable for mounting a circuit board 250. The second body 2 is also provided with a second mounting groove 26 on the side away from the circuit board 250. The second mounting groove 26 is suitable for a driving component 261. The driving component 261 is suitable for driving and connecting the transmission assembly 20 after passing through the second body 2.

[0059] In this embodiment, by installing the circuit board 250 in the first mounting slot 25 and the drive component 261 in the second mounting slot 26, the installation of the circuit board 250 and the drive component 261 is more stable, and the mutual interference between the circuit board 250 and the drive component 261 is reduced, thereby further improving the performance and reliability of the product.

[0060] Specifically, the second body 2 has a first mounting groove 25 on the side near the fourth body 4 for accommodating and fixing the circuit board 250. The opening of the first mounting groove 25 also has several fixing parts 251, which can fit tightly against the edge of the circuit board 250, thus providing stable support and precise positioning for the circuit board 250. This also prevents the circuit board 250 from shifting or loosening due to vibration or external forces during operation, ensuring the stability and reliability of the circuit board 250. The second body 2 also has a second mounting groove 26 on the side away from the circuit board 250, suitable for installing a drive component 261. This drive component 261 (such as a motor) is the core power source of the shaver, transmitting power to the shaving head assembly 50 through the transmission component 20 to achieve the shaving function. After the drive component 261 is installed in the second mounting groove 26, it can be connected to the transmission component 20 through a through hole on the second body 2. This not only ensures efficient power transmission between the drive unit 261 and the transmission assembly 20, but also, through the structural constraint of the second mounting slot 26, keeps the drive unit 261 stable during operation, reducing vibration and noise. The battery assembly 24 is located at the bottom of the drive unit 261 and the circuit board 250, and is positioned between them, cleverly utilizing the lower space of the second body 2. This avoids an increase in product size due to additional space occupation, making the entire shaver housing lighter, more compact, and easier to carry and use. The battery assembly 24's position between the drive unit 261 and the circuit board 250 further optimizes the internal space distribution, acting as a counterweight, making the shaver more stable during use and reducing vibration caused by an unstable center of gravity.

[0061] By mounting the circuit board 250 and the drive unit 261 on opposite sides of the second body 2, functional partitioning is achieved within the first body 1. This maintains a certain spatial distance between the battery assembly 24, the drive unit 261, and the circuit board 250, which facilitates heat dissipation. The circuit board 250 is located closer to the fourth body 4, facilitating electrical connection with external control components (such as the charging assembly 320, switching assembly, etc.) and better protecting it from the heat and vibration generated during the operation of the drive unit 261. The drive unit 261 is mounted on the side away from the circuit board 250 and secured by the second mounting slot 26, ensuring efficient connection with the transmission assembly 20 and providing stable power support for the transmission assembly 20.

[0062] Furthermore, the first body 1 is also provided with a first through hole 13, and the fourth body 4 is also provided with a second through hole 42. The first through hole 13 and the second through hole 42 are also suitable for setting a button assembly 14, which is connected to the contacts on the circuit board 250. Specifically, the button assembly 14 includes a pressing member, an elastic member, a button cap, and a second sealing member; the pressing member is fixedly disposed in the first through hole 13 of the first body 1, and the pressing member has a floating part in the middle, which is suitable for elastic deformation and pressing the contacts on the circuit board 250; the second sealing member is sealed in the first through hole 13; the elastic member elastically connects the second sealing member and the button cap, and the button cap is slidably disposed in the second through hole 42 of the fourth body 4 and pushes the floating part of the pressing member. In this embodiment, when the user presses the button cap, the button cap transmits the pressing force to the floating part of the pressing part through the compression of the elastic element. The floating part then presses the contact on the circuit board 250, triggering the corresponding function operation. During the pressing process, the second sealing element always remains sealed to prevent external impurities from entering. When the user releases the button cap, the elastic element releases energy, pushing the button cap to quickly reset, and the floating part returns to its original state, completing a complete operation process.

[0063] More specifically, the pressing component is fixedly disposed within the first through hole 13 of the first body 1, and its main function is to transmit the external pressing action to the contacts of the internal circuit board 250. A floating part is provided in the middle of the pressing component, which can elastically deform within a certain range. When the user presses the button cap, the floating part presses the contacts on the circuit board 250, thereby triggering the corresponding function operation. The second sealing component is sealed within the first through hole 13, and its main function is to prevent external dust, liquids, and other impurities from entering the shaver through the button assembly 14, thereby protecting the circuit board 250 and other internal components. The second sealing component fits tightly with the pressing component, ensuring that the sealing performance is not affected during pressing, while providing stable support for the elastic component. The elastic component elastically connects the second sealing component and the button cap, and its main function is to provide rebound force to the button cap. When the user presses the button cap, the elastic component is compressed, storing elastic potential energy; when the user releases the button cap, the elastic component releases energy, causing the button cap to quickly return to its initial position. The button cap is slidably disposed in the second through hole 42 of the fourth body 4, and the function is operated by pushing the floating part of the pressing member.

[0064] Further, refer to Figure 1 It also includes a fifth body 5, which is fixedly installed on the top of the first body 1. A cutter head assembly 50 is detachably installed on the top of the fifth body 5. A first seal is also provided between the top of the first body 1 and the bottom of the fifth body 5. The transmission assembly 20 is adapted to pass through the first seal.

[0065] In this embodiment, the fifth body 5 is fixedly disposed on the top of the first body 1 for mounting and supporting the blade assembly 50. The first seal tightly fits the contact surface of the first body 1 and the fifth body 5, effectively preventing dust, liquid and other impurities from entering the shaver from the gap between them, thereby protecting the internal components from contamination and damage.

[0066] Specifically, a fifth body 5 is provided on the first body 1 to better accommodate the blade assembly 50. Since the blade assembly 50 has a large diameter, the diameter of the top of the first body 1 also needs to be large. However, the diameter of the lower part of the first body 1 is smaller for ease of grip. Therefore, a separate fifth body 5 is provided on the top of the first body 1 to allow for the detachable fixing of the blade assembly 50. This separate design of the fifth body 5 and the first body 1 results in a more rational distribution of the product's overall center of gravity. The larger blade assembly 50 prevents the shaver from appearing top-heavy, thus improving stability and comfort during use. Furthermore, the first seal protects the transmission assembly 20 and internal circuitry from external contamination, reducing the risk of malfunctions caused by dust or liquid ingress and extending the product's lifespan.

[0067] Furthermore, this application provides a razor including the housing structure of any of the above embodiments.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
