[0001] The present application relates to the technical field of shavers, in particular to a shaver base shell and an electric shaver. BACKGROUND

[0002] With the continuous development of electric shavers, the volume of shavers is becoming smaller and smaller, making it more convenient for users to carry. Usually, users will place the shaver in the luggage or backpack when going out. Since other items will also be carried in the luggage and backpack, and it is inevitable to produce extrusion or collision during movement, and the protection of the internal electrical components of the shaver mainly relies on the shell, therefore, it is necessary to make the shell of the shaver have high pressure resistance to ensure the safety of the internal motor, battery and head structure.

[0003] In addition, during daily use of the user, there may also be a situation of dropping the shaver out of hand, and the shell of the shaver also needs to have high strength to protect the safety and stability of the internal structure.

[0004] However, since the shell of the shaver is mostly made of plastic, the strength is poor compared to metal, therefore, when the shaver falls or collides with other items, the impact force is easy to cause damage to the shell, thereby causing damage to the internal electrical components, affecting the service life of the whole shaver. CONTENT OF THE INVENTION

[0005] Therefore, it is necessary to provide a shaver base shell and an electric shaver to at least improve the strength of the external base shell, thereby ensuring the stability of the internal structure.

[0006] In order to solve the above technical problems and other problems, according to some embodiments, an aspect of the present application provides a shaver base shell, comprising: a bearing part, a supporting part and a reinforcing part; the supporting part is annular and forms a supporting space, the bearing part is arranged in the supporting space, the supporting part is connected with the bearing part, and at least part of the bearing part is arranged spaced apart from the supporting part to form a buffer cavity; the reinforcing part is arranged on the side of the supporting part away from the bearing part, the reinforcing part is attached to the outer surface of the supporting part, extends from the edge of the supporting part to the middle, and the reinforcing part corresponds to the position of the supporting part corresponding to the buffer cavity.

[0008] In some embodiments, a plurality of reinforcing parts are formed on the first mounting surface and the second mounting surface of the supporting part, and the plurality of reinforcing parts on the first mounting surface and the plurality of reinforcing parts on the second mounting surface are arranged one by one in correspondence.

[0009] In some embodiments, a fastener is further included, the fastener abutting the bearing portion through the supporting portion, and the reinforcing portion abutting the fastener at an end away from the edge of the supporting portion.

[0010] In some embodiments, a connecting rod is further included, the fastener and the reinforcing portion are arranged one-to-one, and the connecting rod is arranged between two fasteners on one side.

[0011] In some embodiments, a through hole is formed at one end of the fastener through the supporting portion, two ends of the connecting rod pass through two fasteners on one side respectively, and are connected with the fasteners.

[0012] In some embodiments, the fastener includes a screwing portion and an abutting portion, the abutting portion passes through the supporting portion, the through hole is formed on the abutting portion, the screwing portion protrudes from the outer surface of the supporting portion, and the reinforcing portion abuts the screwing portion at an end away from the edge of the supporting portion.

[0013] In some embodiments, the abutting portion has a rectangular cross section, the supporting portion has a positioning hole corresponding to the position of the fastener, and the positioning hole is a rectangular hole.

[0014] In some embodiments, a reinforcing column is further included, the reinforcing column extends along the thickness direction of the shaver base shell and is arranged at the folding angle of the bearing portion, and the reinforcing portion abuts the reinforcing column at an end away from the fastener.

[0016] In the shaver base shell and the electric shaver of the above embodiments, the supporting portion is annular, and at least part of the bearing portion is arranged spaced apart from the supporting portion, so that a buffer cavity can be formed between the supporting portion and the bearing portion, and the impact force when impacted can be absorbed by the buffer cavity to reduce the impact of the impact force on the electrical components of the shaver carried in the bearing portion.

Therefore, on the one hand, the reinforcing portion can improve the support of the supporting portion and ensure the overall strength of the supporting portion, and on the other hand, since the reinforcing portion is arranged corresponding to the buffer cavity and the buffer cavity is a hollow cavity, the reinforcing portion can reduce the problem of the supporting portion corresponding to the buffer cavity being concave to a certain extent, and ensure the stability of the overall base shell structure.

[0030] As Figure 1 In combination Figure 2 As shown in the embodiment provided by the present application, the razor base provides a razor base, which comprises a bearing part 1, a supporting part 2 and a reinforcing part 3. The supporting part 2 is annular and forms a supporting space. The bearing part 1 is arranged in the supporting space. The supporting part 2 is connected with the bearing part 1, and at least part of the bearing part 1 is arranged spaced apart from the supporting part 2 to form a buffer cavity 101. The reinforcing part 3 is arranged on the side of the supporting part 2 away from the bearing part 1. The reinforcing part 3 is in close contact with the outer surface of the supporting part 2 and extends from the edge of the supporting part 2 to the middle. The reinforcing part 3 corresponds to the position of the supporting part 2 reinforcing the buffer cavity 101.

[0031] The present application sets the annular supporting part 2, and at least part of the bearing part 1 is arranged spaced apart from the supporting part 2, so as to form the buffer cavity 101 between the supporting part 2 and the bearing part 1. Then, the impact force when impacted can be absorbed by the buffer cavity 101, so as to reduce the influence of the impact force on the electrical components of the razor carried in the bearing part 1.

[0032] Further, the reinforcing part 3 is arranged outside the supporting part 2, i.e. on the side of the supporting part 2 away from the bearing part 1, and is attached to the outer surface of the supporting part 2 and extends from the edge of the supporting part 2 to the middle, and corresponds to the position of the buffer cavity 101. Thus, on the one hand, the reinforcing part 3 can improve the support of the supporting part 2 and ensure the overall strength of the supporting part 2. On the other hand, since the reinforcing part 3 is arranged corresponding to the buffer cavity 101 and the buffer cavity 101 is a hollow cavity, the buffer cavity 101 is prone to indentation under impact. Thus, the reinforcing part 3 can reduce the problem of indentation of the supporting part 2 corresponding to the buffer cavity 101 to some extent, and ensure the stability of the overall base structure.

[0033] Optionally, as shown in Figure 2 In combination Figure 3 The reinforcing part 3 in the present application is in a strip shape, and the width of the reinforcing part 3 gradually increases from the edge of the supporting part 2 to the middle.

[0034] Since the reinforcing part 3 needs to be adapted to the shape of the supporting part 2, and the installation area of the reinforcing part 3 at the corner is small, by making the width of the reinforcing part 3 at the connection position with the edge of the supporting part 2 small, it can be ensured that the reinforcing part 3 will not exceed the range of the supporting part 2. At the same time, by gradually increasing the width of the reinforcing part 3 from the edge of the supporting part 2 to the center area, the reinforcing part 3 can have higher bearing capacity, thereby ensuring the support of the supporting part 2 and improving the stability of the overall structure.

[0035] In some embodiments, as shown in Figures 1-3 The first mounting surface and the second mounting surface of the supporting part 2 in the present application are each formed with a plurality of reinforcing parts 3, and the plurality of reinforcing parts 3 on the first mounting surface and the plurality of reinforcing parts 3 on the second mounting surface are arranged one-to-one.

[0036] The first mounting surface and the second mounting surface in the present application correspond to the front surface and the back surface of the overall electric shaver. In fact, the front surface and the back surface of the electric shaver provided in the present application have the same structure and shape, so the above-mentioned front surface and back surface refer to two large contact surfaces. By forming the reinforcing part 3 on the first mounting surface and the second mounting surface and arranging the reinforcing part 3 one-to-one, the stress uniformity and stability of the overall structure can be ensured.

[0037] In some embodiments, as shown in Figure 1 In combination Figure 2 Further, the fastener 4 passes through the supporting part 2 and abuts against the bearing part 1, and one end of the reinforcing part 3 away from the edge of the supporting part 2 abuts against the fastener 4.

[0038] Preferably, the fastener 4 in the present application adopts a bolt, and correspondingly, the supporting part 2 is formed with a screw hole corresponding to the position of the fastener 4, so as to realize the abutment of the fastener 4 and the outer wall surface of the bearing part 1 through thread cooperation.

[0039] And through the setting of the fastener 4, the reinforcing part 3 can be in abutment with the fastener 4 at one end away from the edge of the support part 2, so that when the overall shaver is under pressure, the reinforcing part 3 can transmit the force to the fastener 4, thereby improving the stability of the reinforcing part 3 to a certain extent.

[0040] In some embodiments, as shown in Figure 1 In combination Figure 4 It is also shown that the connecting rod 6 is provided, and the fastener 4 is provided in one-to-one correspondence with the reinforcing part 3, and the connecting rod 6 is provided between the two fasteners 4 on one side.

[0041] By providing the connecting rod 6, the two fasteners 4 on one side can be connected in series, thereby forming a more stable support structure, and therefore, through the fastener 4, an abutting force can be provided for the two reinforcing parts 3 opposite to each other, thereby ensuring the stability of the opposite reinforcing parts 3 in the length direction of the base shell, and through the connecting rod 6, the two fasteners 4 on one side can be connected in series, thereby ensuring the stability of the two reinforcing parts 3 on one side in the width direction of the base shell, and further ensuring the stability and strength of the overall support part 2. Figure 1

[0042] In some embodiments, as shown in Figure 4 The fastener 4 passes through one end of the support part 2 to form a through hole 4021, and the two ends of the connecting rod 6 pass through the two fasteners 4 on one side and are connected with the fasteners 4.

[0043] Optionally, as shown in Figure 4 The fastener 4 in the present application includes a screwing part 401 and an abutting part 402, the abutting part 402 passes through the support part 2, the through hole 4021 is formed on the abutting part 402, and the screwing part 401 protrudes from the outer surface of the support part 2. One end of the reinforcing part 3 away from the edge of the support part 2 is in abutment with the screwing part 401.

[0044] Through the screwing part 401, the fastener 4 can be rotated relative to the support part 2 to a certain extent, so as to loosen the fastener 4, and then the fastener 4 can be pulled out after the connecting rod 6 is removed, which facilitates assembly or maintenance and maintenance during subsequent use of the user.

[0045] In some embodiments, as shown in Figure 4 The abutting part 402 in the present application has a rectangular cross section, and the support part 2 has a positioning hole 201 corresponding to the position of the fastener 4, and the positioning hole 201 is a rectangular hole.

[0046] ​The abutment 402 provided in this application has a rectangular columnar structure and a smooth outer wall surface without threads. Correspondingly, the positioning hole 201 formed by the support part 2 at the position of the fastener 4 is also a rectangular through hole 4021. During assembly, the abutment 402 is first inserted into the positioning hole 201, and then the connecting rod 6 is passed through the through holes 4021 formed on the two abutment parts 402 at one time, thereby realizing the connection between the two fasteners 4 and the assembly of the connecting rod 6. The connecting rod 6 can prevent the fastener 4 from detaching from the support part 2 and ensure the stability of the position of the fastener 4.

[0047] Preferably, such as Figure 4 As shown, the abutment portion 402 in this application also has a receiving portion and a guide hole 4023. The diameter of the receiving portion is larger than the diameter of the connecting rod 6, and the two ends of the guide hole 4023 are respectively connected to the receiving portion and the positioning hole 201. The diameter of the positioning hole 201 is equal to or slightly smaller than the diameter of the connecting rod 6. Therefore, during assembly, the connecting rod 6 can be passed through the receiving portion first, and then the connecting rod 6 can be pressed down to make the connecting rod 6 enter the guide hole 4023 and finally enter the positioning hole 201. Since the diameter of the positioning hole 201 is smaller than or equal to the diameter of the connecting rod 6, the connecting rod 6 can be tightly fitted with the positioning hole 201, thereby ensuring the stability of the fastener 4.

[0048] In some embodiments, such as Figures 1-3 As shown, it also includes a reinforcing post 5, which extends along the thickness direction of the shaver base shell and is disposed at the corner of the bearing portion 1; the end of the reinforcing portion 3 away from the fastener 4 is connected to the reinforcing post 5.

[0049] In this application, the reinforcing column 5 protrudes from the edge of the base shell, so that it can make contact with the reinforcing column 5 first, thereby weakening or sharing the impact force and further ensuring the stability of the base shell.

[0050] Furthermore, since the other end of the reinforcing part 3 in this application is connected to the reinforcing column 5, the force on the reinforcing part 3 can be distributed to the reinforcing column 5 and the fastener 4 through the reinforcing column 5 and the fastener 4, thereby improving the stability of the overall structure.

[0051] Another aspect of this application provides an electric shaver that includes the shaver housing in any of the above embodiments.

[0052] Electric shavers using the shaver housing provided in this application have a more stable housing structure, which can ensure the stability of electrical components such as motors, batteries, and circuit boards inside the shaver, avoid the problem of the housing being damaged by impact and squeezing the internal electrical components, and improve the stability and lifespan of the shaver.

[0053] Please note that the above embodiments are only for illustrative purposes and do not mean to limit the utility model.

[0054] Each embodiment in the specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between each embodiment can be referred to each other.

[0055] Each technical feature of the above embodiments can be combined arbitrarily, and in order to make the description simple, each technical feature in the above embodiments is not described in all possible combinations, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the specification.

[0056] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as the limitation of the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are all within the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
