DETAILED DESCRIPTION
[0024] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.
[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.
[0026] As Figures 1-5 shown, a handle of a shaving razor, comprising:
[0027] A handle body 100, the handle body 100 is provided with an accommodating cavity 101, and the accommodating cavity 101 is provided with a switch button 102;
[0028] A switch operating part 103, a through connecting counterbore 104 is arranged on the cavity wall of the accommodating cavity 101, the switch operating part 103 is arranged in the connecting counterbore 104, and the switch operating part 103 is injection-molded connected with the connecting counterbore 104, the material of the switch operating part 103 is an elastic material, and after the switch operating part 103 is stressed and recessed inward, the switch operating part 103 can abut and connect with the switch button 102 to change the working state of the switch button 102.
[0029] In this embodiment, the design of the receiving cavity 101 inside the handle body 100 provides an excellent protective environment for the switch button 102, effectively preventing the intrusion of external contaminants such as dust and liquids, thereby significantly improving the reliability and service life of the device. In particular, a through-hole connecting countersunk hole 104 is provided on the cavity wall of the receiving cavity 101, and the switch operating part 103 made of elastic material is directly connected to it by injection molding. This design abandons the traditional sealing ring method. Compared with the traditional sealing ring connection, the injection-molded switch operating part 103 and the handle body 100 form a seamless connection, which greatly improves the sealing level of the entire device, avoids the sealing failure problem caused by the aging or displacement of the sealing ring, and also reduces the use of additional parts, simplifying the production process.
[0030] like Figure 3 As shown, in a further preferred embodiment, an anti-detachment ring 105 is integrally provided at the bottom of the switch operation part 103, and an anti-detachment cavity is formed between the anti-detachment ring 105 and the switch operation part 103, and the through hole wall of the connecting countersunk hole 104 is stuck in the anti-detachment cavity.
[0031] In this embodiment, by inserting the through-hole wall of the connecting countersunk hole 104 into the anti-detachment cavity formed by the anti-detachment ring 105 and the switch operating part 103, it is ensured that the switch operating part 103 will not easily fall off or loosen from its installation position, and can remain stable even under frequent use or external impact; and the presence of the anti-detachment ring 105 increases the connection area between the switch operating part 103 and the handle body 100, further enhancing the overall sealing performance.
[0032] In a further preferred embodiment, a deformation cavity 106 is provided on the inner side of the switch operation part 103, and an abutting protrusion 107 is provided in the deformation cavity 106. When the switch operation part 103 is forced to be recessed, the abutting protrusion 107 can contact and connect with the switch button 102 to change the working state of the switch button 102.
[0033] In this embodiment, a deformation cavity 106 is provided on the inner side of the switch operation part 103, and an abutment protrusion 107 is disposed inside the deformation cavity 106. When the user applies pressure to the switch operation part 103, the switch operation part 103 can be recessed inward, thereby allowing the abutment protrusion 107 to accurately contact the switch button 102 and trigger a change in its working state. The presence of the deformation cavity 106 allows the switch operation part 103 to undergo moderate deformation when subjected to force, while the contact between the abutment protrusion 107 and the switch button 102 provides clear tactile feedback.
[0034] It is worth mentioning that the design of the deformable cavity 106 allows its shape and size to be adjusted according to specific application needs, so as to adapt to different operating force requirements. It can achieve both gentle touch control and application scenarios that require greater pressing force, thus enhancing the applicability of the product.
[0035] Preferably, the first end of the handle body 100 is used to connect with the shaver 200, the second end of the handle body 100 is provided with a charging port 108, and the handle body 100 is also provided with a waterproof cover 113 for plugging and fixing the charging port 108.
[0036] In this embodiment, a charging port 108 is provided at the second end of the handle body 100, which makes it convenient for users to charge the device at any time. The waterproof cover 113 can not only effectively prevent water, dust and other contaminants from entering the charging port 108 when the charging function is not in use, avoiding electrical failures caused by external environmental factors, but also protect the charging interface from physical damage, such as scratches or collisions.
[0037] It is worth mentioning that the charging port 108 is located on the second end of the controller body 100, which can be adapted to the charging base. The controller body 100 can be plugged into the charging base to realize the charging function.
[0038] It should be noted that the switch operation unit 103 is configured to be turned on or off by long press to avoid the risk of accidental touch. During the operation of the shaving and trimming device, the working level of the shaving and trimming device can be adjusted by pressing the switch operation unit 103. A digital display screen 109 is injection molded on the handle body 100 and electrically connected to the battery to display the battery level in the handle body 100. When the battery level is lower than 20%, the buzzer on the digital display screen 109 will emit an audible reminder.
[0039] Furthermore, the handle body 100 is covered with a disposable protective cover; the disposable protective cover can be replaced after each use, effectively avoiding the risk of cross-infection between different users, which is especially important in medical or public use environments; this means that simply changing the protective cover can keep the device clean, reducing the workload and complexity of cleaning and disinfection.
[0040] Preferably, a portion of the handle body 100 is recessed inward to form a finger grip area 110, which is disposed opposite to the switch operation part 103.
[0041] In this embodiment, by providing an inwardly recessed finger grip area 110 on the handle body 100, the user can naturally find and grip the most suitable position during use, improving the stability and comfort of the handheld device, especially during long-term use, effectively reducing hand fatigue; and the design of the finger grip area 110 being positioned opposite to the switch operation part 103 ensures that while the user is holding the device, their fingers can naturally rest on the switch operation part 103, allowing for easy operation of the switch without adjusting gestures or moving the palm, improving the convenience of operation, as well as increasing the accuracy and response speed of operation.
[0042] Preferably, anti-slip pads 111 are provided on both sides of the switch operation part 103.
[0043] It is worth mentioning that the anti-detachment ring 105 and the anti-slip pad 111 are connected as one piece.
[0044] In this embodiment, the anti-slip pad 111 can increase the friction between the hand and the switch operation part 103, making the user more stable during operation and reducing finger slippage caused by hand sweat or slippery conditions. The anti-slip pad 111 also helps the user to more accurately locate and operate the switch button 102, allowing operation by touch even without direct visual confirmation, thus improving the accuracy and efficiency of operation. Furthermore, when used with a disposable protective cover, the anti-slip pad 111 can also increase the friction with the disposable protective cover, preventing relative slippage between the two.
[0045] like Figures 4-5 Preferably, a planar abutment area 112 is formed on the second end surface of the handle body 100. When the handle body 100 is placed on the placement plane, the planar abutment area 112 on the handle body 100 is in contact with the placement plane; and the planar abutment area 112 is disposed opposite to the switch operation part 103.
[0046] In this embodiment, the design of the flat contact area 112 enables the handle to remain stable on the placement surface and prevents it from easily rolling or tipping over. Since the flat contact area 112 is arranged opposite to the switch operation part 103, the switch operation part 103 will not directly contact the placement surface when the device is placed, avoiding accidental activation or damage caused by accidental touch or other external forces. When it is necessary to temporarily place the device, the safety and accessibility of the device are ensured.
[0047] Preferably, the first end of the surface where the switch operation part 103 is located forms a gradual change such that the closer the surface is to the first end, the closer the linear distance between the surface and the axis of the handle body 100 becomes.
[0048] In this embodiment, the surface where the switch operation part 103 is located adopts a gradient design, that is, starting from the first end of the surface, the distance between it and the handle body 100 along the axial line gradually decreases as it approaches the first end; this effectively reduces the obstruction of the handle's view to the user. This means that when the user holds the device to shave or trim, they can see the working area of the razor 200 more clearly, observe the specific area to be treated and the working status of the razor head, thereby improving the accuracy and efficiency of operation.
[0049] like Figure 6 As shown, a prep shaver includes the aforementioned prep shaver handle and a shaver 200. The shaver 200 is detachably connected to the prep shaver handle, allowing users to easily remove the shaver 200 from the handle for cleaning, disinfection, or replacement. Moreover, the detachable design allows users to select different types of shavers 200 according to different usage needs, increasing the product's applicability and flexibility.
[0050] It is worth mentioning that the handle body 100 is provided with a connecting cover 114 for connecting the razor 200.
