Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a new type of reciprocating electric shaver. Background Art

[0002] A razor is a personal care tool used to shave facial beards and is widely used in men's daily lives. With the development of technology, the types and functions of razors are becoming increasingly diverse, from traditional manual razors to modern electric razors, each type has its own unique characteristics and applicable scenarios.

[0003] Among them, the reciprocating electric shaver shaves the beard through the reciprocating motion of the blade head, which is suitable for delicate beard scenes.

[0004] Existing reciprocating electric shavers usually use a motor to drive a cam to make the transmission block reciprocate. In order to ensure the stable reciprocating translation of the transmission block, complicated parts need to be set on the shaver, such as a guide rod for the transmission guide. Since the guide rod is installed separately, the entire shaver is complicated to install and difficult to assemble and disassemble.

[0005] For example, the Chinese patent CN118596207A provides a "parallel swing motion structure and a razor using the same". The above patent includes a swing rod, on which a first protrusion is provided for connecting / setting an external cutter head, and the cutter head is used to cut hair or beards when performing a swing motion; it also includes a first block provided on the swing rod and a first rod body slidably arranged in cooperation with the first block, the first rod body being used to be mounted on an external housing, and the swing rod performs a swing motion along the length direction of the first rod body via the first block. By means of the first block provided on the swing rod and the first rod body slidably arranged in cooperation with the first block, it is ensured that the swing rod performs a smooth swing motion along the length direction of the first rod body during the process of cutting hair or beards, and the swing rod slides on the first rod body via the first block, thereby reducing the friction between the swing rod and other components and avoiding excessive wear.

[0006] The above patent also has the problem of complex structure, which makes the whole shaver difficult to assemble. Summary of the invention

[0012] In the above-mentioned new reciprocating electric shaver, the lower part of the transmission block has a protruding guide cylinder, and the above-mentioned guide rod is inserted into the guide cylinder.

[0013] In the above-mentioned new reciprocating electric shaver, there are two guide rods, which are symmetrically arranged on both sides of the cam, and the lower part of the transmission block has guide cylinders corresponding to the guide rods one by one.

[0014] In the above-mentioned new reciprocating electric shaver, the above-mentioned movement bracket matches the inside of the shell, the movement bracket is fixedly connected in the shell, and also includes a fixed bracket connected to the upper part of the movement bracket, the above-mentioned transmission mechanism is connected to the fixed bracket, and the driving member is connected to the lower part of the movement bracket.

[0015] In the above-mentioned new reciprocating electric shaver, the interior of the fixed bracket is a hollow cavity with an opening at the upper end, and two guide rods are respectively penetrated and connected at the two ends of the fixed bracket. The fixed bracket, the guide rods and the transmission block form an installation unit, and the installation unit is connected to the upper part of the movement bracket through fasteners. The inner cavity size of the fixed bracket is larger than the width size of the transmission block.

[0016] In the above-mentioned new reciprocating electric shaver, a plurality of baffles are fixedly connected to the movement bracket, two of which are respectively against the two ends of one of the guide rods, and the other two baffles are respectively against the two ends of the other guide rod.

[0017] In the above-mentioned novel reciprocating electric shaver, a deformable sealing sleeve is connected between the transmission block and the fixed bracket.

[0020] In the above-mentioned novel reciprocating electric shaver, a waterproof sealing ring is provided between the electric plug and the charging port.

[0021] In the above-mentioned new reciprocating electric shaver, the edge of the connecting plate has a convex edge protruding upward in an annular manner, and a collecting chamber with a hollow interior and an open top is formed between the convex edge and the upper portion of the connecting plate.

[0024] Compared with the prior art, the cam of the novel reciprocating electric shaver is always in contact with the transmission block, thus effectively avoiding sudden rigid contact between the cam and the transmission block, effectively reducing noise and improving its stability.

[0025] Since the guide rod, the transmission block and the fixed bracket can form an independent component unit, the fasteners can not only stably connect the connecting plate, the fixed bracket and the movement bracket, but also stably position the fixed bracket between the movement bracket and the connecting plate. Moreover, the guide rod is limited after the component unit is installed. Therefore, the entire shaver is not only easy to load and unload, but also compact in structure and has high practical value.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0037] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 and Figure 7 As shown, the new reciprocating electric shaver comprises a housing 1, a driving member 2, a transmission mechanism and a cutter head 3. The interior of the housing 1 is a cavity and the upper end is open. The cutter head 3 is connected to the upper end opening of the housing 1. The driving member 2 and the transmission mechanism are both located in the housing 1. The power output by the driving member 2 can cause the cutter head 3 to reciprocate after passing through the transmission mechanism. The transmission mechanism comprises a cam 4, a guide rod 5 and a transmission block 6. The guide rod 5 is laterally fixed to the housing 1, the transmission block 6 is located at the opening of the housing 1 and the middle part of the guide rod 5 is penetrated by the transmission block 6. The lower part of the transmission block 6 has a long strip-shaped groove 6b. The lower end of the cam 4 is fixed to the driving member 2, and the upper end of the cam 4 is embedded in the groove 6b.

[0038] The housing 1 is also connected with a movement bracket 7 and a fixing bracket 8 for positioning the transmission mechanism.

[0039] The guide rod 5 is in the shape of a straight rod, and the upper end of the cam 4 is embedded in the groove 6b at the lower part of the transmission block 6. This structure can ensure that the cam 4 is always in contact with the transmission block 6. During operation, the cam 4 will not suddenly and rigidly touch the transmission block 6, which not only reduces noise but also has relatively high overall stability.

[0040] The transmission block 6 is connected to the cutter head. Since the structure of the cutter head and the connection structure between the transmission block 6 and the cutter head are both existing technologies, this part of the technical features will not be repeated in the embodiment. This patent focuses on how to drive the transmission block 6 to reciprocate and translate.

[0041] Specifically, when the driving member 2 drives the cam 4 to rotate continuously, the cam 4 drives the transmission block 6 to swing. However, the transmission block 6 is connected to the guide rod 5, and the guide rod 5 limits the swing of the transmission block 6, so the transmission block 6 can only reciprocate along the guide rod 5.

[0042] Since the transmission block 6 is connected to the cutter head 3, the cutter head 3 can eventually move back and forth quickly, thereby completing the shaving operation.

[0043] The transmission block 6 has a protruding guide cylinder 6a at its lower portion, and the guide rod 5 is passed through the guide cylinder 6a.

[0044] There are two guide rods 5 , which are symmetrically arranged on both sides of the cam 4 . The lower part of the transmission block 6 has a guide cylinder 6 a corresponding to the guide rods 5 one by one.

[0045] The two guide rods 5 are respectively connected to the corresponding guide cylinders 6 a . Such a structure enables the transmission block 6 to translate stably along the guide rods 5 .

[0046] The movement bracket 7 matches the interior of the housing 1 , is fixedly connected to the housing 1 , and further comprises a fixed bracket 8 connected to the upper portion of the movement bracket 7 , the transmission mechanism is connected to the fixed bracket 7 , and the driving member 2 is connected to the lower portion of the movement bracket 7 .

[0047] The movement bracket 7 has two functions:

[0048] First, provide enough space for the fixed bracket 8 to be connected and set;

[0049] Second, provide enough space for the drive member 2 to be connected and set.

[0050] In this embodiment, the movement bracket 7 is connected to the port of the housing 1 through a fastener.

[0051] Since the fixed bracket 8 is located at the upper part of the movement bracket 7, the driving member 2 is located at the lower part of the movement bracket 7. Therefore, such a structure can make the driving member 2 relatively independent from the fixed bracket 8, effectively improving the stability and compactness of the entire shaver.

[0052] The interior of the fixed bracket 8 is a hollow cavity with an open upper end. Two guide rods 5 are respectively penetrated and connected at both ends of the fixed bracket 8. The fixed bracket 8, the guide rods 5 and the transmission block 6 form an installation unit, and the installation unit is connected to the upper part of the movement bracket 7 through fasteners. The inner cavity size of the fixed bracket 8 is larger than the width size of the transmission block 6.

[0053] The guide rod 5 is connected to the inner cavity of the fixed bracket 8, which effectively improves the compactness of the structure. The fixed bracket 8, the guide rod 5 and the transmission block 6 form an independent installation unit. After the installation unit is assembled, it is installed in the movement bracket 7, which simplifies the assembly process and is easy to assemble.

[0054] A plurality of baffles 9 are fixedly connected to the movement bracket 7 , wherein two baffles 9 are respectively abutted against two ends of one of the guide rods 5 , and the other two baffles 9 are respectively abutted against two ends of the other guide rod 5 .

[0055] After the mounting unit is loaded into the movement bracket 7, the two baffles on the movement bracket 7 are just located at the two ends of the guide rod 5. In other words, once the mounting unit is loaded into the movement bracket 7, the guide rod 5 can be limited.

[0056] A deformable sealing sleeve 10 is connected between the transmission block 6 and the fixing bracket 8 .

[0057] The sealing sleeve 10 is made of a flexible rubber material, and the sealing sleeve 10 will not hinder the normal movement of the transmission block 6 and can also prevent dust and impurities from entering the transmission mechanism.

[0058] A waterproof sealing ring 11 is provided between the movement bracket 7 and the housing 1 .

[0059] The waterproof sealing ring 11 can effectively improve the waterproof performance of the connection between the movement support 7 and the housing 1, that is, provide waterproof performance for the entire upper part of the shaver.

[0060] The bottom of the shell 1 has a charging port 1a passing through it, the lower part of the movement bracket 7 has a positioning cylinder 7a for positioning the driving member 2, the side of the positioning cylinder 7a has a positioning cylinder 2 7b for positioning the battery, the lower part of the positioning cylinder 7a is connected to a positioning plate 7b1, the positioning plate 7b1 is connected to an electric plug 12 electrically connected to the battery, and the above-mentioned electric plug 12 is embedded in the charging port 1a.

[0061] The driving member 2 is a motor. After the driving member 2 is installed in the positioning tube 7a, it not only protects the motor but also can position the motor.

[0062] In this embodiment, a flexible sealing ring is provided between the rotating shaft of the motor and the fixing bracket 8 .

[0063] Similarly, the positioning tube 2 7b can not only protect the battery, but also can position the battery. Of course, the battery in the present embodiment is a rechargeable rechargeable battery.

[0064] The electrical plug 12 is a commonly used TYPE C interface.

[0065] A waterproof sealing ring 11 is provided between the electrical plug 12 and the charging port 1 a.

[0066] The waterproof sealing ring 11 here can effectively improve the waterproof performance between the electric plug 12 and the charging port 1 a , that is, effectively improve the waterproof performance of the lower part of the housing 1 .

[0067] It also includes a connecting plate 13 and a fastener 14. The connecting plate 13 is located at the upper part of the movement bracket 7. The fastener 14 is penetrated through the connecting plate 13, the fixed bracket 8 and the movement bracket 7 and fixedly connects the connecting plate 13, the fixed bracket 8 and the movement bracket 7. The fixed bracket 8 is tightly pressed between the connecting plate 13 and the movement bracket 7.

[0068] The fasteners 14 can not only stably connect the connecting plate 13, the fixing bracket 8 and the movement bracket 7, but also stably position the fixing bracket 8 between the connecting plate 13 and the movement bracket 7.

[0069] The connection structure is compact and has high stability.

[0070] The edge of the connecting plate 13 has an upwardly protruding convex edge 13a, and a collecting chamber 13b with a hollow interior and an open top is formed between the convex edge 13a and the upper portion of the connecting plate 13. The connecting plate 13 has a through avoidance opening 13c, and the above-mentioned fixed bracket 8 is embedded in the avoidance opening 13c.

[0071] During the shaving process, tiny beard impurities fall into the collecting chamber 13b. After the cutter head 3 is opened, the impurities in the collecting chamber 13b can be conveniently processed.

[0072] The sealing sleeve 10 is sleeved on the transmission block 6 , and the outer edge of the sealing sleeve 10 is tightly pressed between the connecting plate 13 and the fixing bracket 8 .

[0073] Such a structure enables the sealing sleeve 10 to be stably connected to the transmission block 6 .

[0074] The cutter head 3 includes a cutter seat 3a and a blade 3b movably connected to the cutter seat 3a. The cutter seat 3a is connected to the upper part of the connecting plate 13, and also includes a magnet 15 and a magnet 2 16. The movement bracket 7 has a recessed magnet seat 1 7c. The magnet 15 is embedded in the magnet seat 1 7c and the magnet 15 is tightly pressed between the connecting plate 13 and the movement bracket 7. The cutter seat 3a has a magnet seat 2 3a1 with a side opening. The magnet 2 16 is embedded in the magnet seat 2 3a1. The magnet 15 is opposite to the magnet 2 16 and under the magnetic force of the magnet 15 and the magnet 2 16, the cutter seat 3a is stably snap-fitted and embedded in the collecting chamber 13b.

[0075] The knife seat 3a has two functions:

[0076] First, the upper portion of the blade holder 3a is used to connect the blade 3b;

[0077] Secondly, the lower part of the knife seat 3a is used to connect the second magnet 16.

[0078] Since magnet one 15 is positioned between the connecting plate 13 and the movement bracket 7, and magnet one 15 and magnet two 16 are facing each other, when the knife seat 3a is connected to the upper part of the connecting plate 13, the knife seat 3a can be stably connected to the connecting plate 13 under the magnetic attraction of magnet one 15 and magnet two 16.

[0079] Since the cam 4 of the novel reciprocating electric shaver is always in contact with the transmission block 6, sudden rigid contact between the cam 4 and the transmission block 6 is effectively avoided, noise is effectively reduced, and stability is improved.

[0080] Since the guide rod 5, the transmission block 6 and the fixed bracket 8 can form an independent component unit, the fastener 14 can not only stably connect the connecting plate 13, the fixed bracket 8 and the movement bracket 7, but also stably position the fixed bracket 8 between the movement bracket 7 and the connecting plate 13. Moreover, after the component unit is installed, the guide rod 5 is limited. Therefore, the whole shaver is not only easy to load and unload, but also compact in structure and has high practical value.

[0081] Under the magnetic force of magnet 15 and magnet 2 16 , the knife seat 3 a is stably embedded in the collecting cavity of the connecting plate 13 .

[0082] During the use of the shaver, some beard impurities fall into the collecting chamber 13b.

[0083] It can be seen that the cutter head 3 and the housing 1 can be easily disassembled. Once the cutter head 3 is disassembled, the collecting chamber 13b is exposed to the outside, and the impurities in the collecting chamber 13b can be easily cleaned.

[0084] At the same time, the movement bracket 7 has the function of positioning and fixing the bracket 8, the driving member 2 and the battery, so the entire shaver structure is relatively compact.

[0085] Since the cam of the reciprocating new electric shaver is always in contact with the transmission block due to the guide rod, sudden rigid contact between the cam and the transmission block can be effectively avoided, noise can be effectively reduced, and stability can be improved.

[0086] Since the guide rod, the transmission block and the fixed bracket can form an independent component unit, after the component unit is connected to the cover plate through fasteners, the guide rod can be directly limited. It is easy to load and unload, has a compact structure, and has high practical value.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
