[0003] The hair cutter usually comprises an outer shell, an internal component unit installed in the outer shell, and a blade unit installed at the head of the outer shell. Before subsequent assembly and installation, in order to avoid the influence of the external environment on the internal components of the hair cutter, the internal part of the internal component unit needs to be tested for air tightness.

[0004] REFERENCE Figure 1 , Figure 1 The internal component unit 100 required to be tested for air tightness in the present application comprises a shell 101 and a motor part at the front end of the shell 100, and a part of components and elements installed in the shell 101. The side surface of the shell 101 is provided with a key mounting hole 102, and the bottom of the shell 101 is provided with a charging pin mounting hole 103, which is symmetrically arranged on the left and right sides.

[0005] Before the air tightness test, the charging pin mounting hole at the bottom needs to be blocked, and then the inside of the shell is blown through the key mounting hole at the side to test and judge the air tightness in turn. At present, the test work is usually performed by manual operation, and the test process is unstable, which seriously affects the test result. Therefore, further improvement can be made. CONTENT OF THE UTILITY MODEL

[0007] The hair cutter sealing test device provided by the present application adopts the following technical scheme:

[0008] A hair cutter sealing test device comprises a test table, a positioning seat is installed on the test table, and is used for positioning and placing the internal component unit to be tested, and the charging pin mounting hole faces right and the key mounting hole faces up; a horizontal moving seat capable of moving left and right is installed on the right side of the positioning seat, a sealing needle is installed on the side of the horizontal moving seat facing the positioning seat, and the sealing needle is aligned with the charging pin mounting hole; a lifting moving seat capable of lifting control is installed above the positioning seat, a first positioning rod is installed on the lifting moving seat, the first positioning rod is in the form of a hollow pipe and is aligned with the key mounting hole.

[0009] By adopting the technical scheme, during the testing process, the internal component unit to be tested is horizontally placed in the positioning seat, the charging nail mounting hole faces right, and the key mounting hole faces up. Then, the lifting moving seat is controlled to move downward, so that the first positioning rod is pressed against the top of the internal component unit and is aligned with the key mounting hole. Next, the horizontal moving seat is controlled to move toward the positioning seat, so that the sealing needle abuts against the side of the internal component unit and blocks the charging nail mounting hole. Finally, the air pipe is used to inflate the inside of the shell of the internal component unit through the first positioning rod, so as to test the air tightness. The testing process is relatively stable, and the test result can be guaranteed.

[0010] Optionally, the lifting moving seat comprises a first part and a second part, the second part is mounted on the first part through a third part, and the second part can be adjusted to move forward and backward relative to the first part; the first positioning rod is mounted on the second part and can be adjusted to move left and right and up and down relative to the second part.

[0011] By adopting the technical scheme, since the second part can be adjusted to move forward and backward relative to the first part, and the first positioning rod can be adjusted to move left and right and up and down relative to the second part, during the actual installation of the first positioning rod, the first positioning rod can be adjusted in the forward and backward direction, the left and right direction, and the up and down direction, so that the first part can be aligned with the key mounting hole, and subsequent sealing and inflation testing can be performed.

[0012] Optionally, a second positioning rod is further mounted on the second part, the second positioning rod is arranged in parallel with the first positioning rod, and the second positioning rod can also be adjusted to move left and right and up and down.

[0013] By adopting the technical scheme, by arranging the second positioning rod, when the first positioning rod is pressed against the top of the internal component unit, the second positioning rod is also pressed against the top of the internal component unit at the same time, so as to further improve the positioning effect on the internal component unit, so that the internal component unit is not easy to jump vertically during the actual testing process, so as to guarantee the stability and reliability of the testing.

[0014] Optionally, a first longitudinal slot is formed in the first part, one end of the third part is fixedly connected to the second part, the other end of the third part extends to the bottom of the first longitudinal slot in the first part, and is locked and fixed in the first longitudinal slot through a screw.

[0015] By adopting the technical scheme, during the installation process, the screw is loosened, so that the second part and the third part can be adjusted in the direction of the first longitudinal slot at the same time, so that the first positioning rod on the second part can be adjusted in the forward and backward direction.

[0016] Optionally, the second component is formed with a second longitudinal groove extending in the transverse direction, the first positioning rod is in the form of a hollow screw rod, the first positioning rod is installed in the second longitudinal groove, and the upper and lower ends of the first positioning rod are clamped and fixed to the second component by means of nuts.

[0018] Optionally, the bottom of the first positioning rod and the bottom of the second positioning rod are provided with rubber pads, and the rubber pad in the first positioning rod is in the form of a hollow.

[0019] By adopting the above technical scheme, by providing the rubber pads at the bottom of the first positioning rod and the second positioning rod, on the one hand, the shell of the internal component unit can be protected, so that the shell of the first positioning rod and the second positioning rod is not easily damaged during pressing. On the other hand, after the second positioning rod is pressed, the rubber pad can seal the outer periphery of the key mounting hole below, so that air leakage does not easily occur during subsequent inflation, so as to ensure the test effect.

[0020] Optionally, the end of the sealing needle is provided with a rubber sealing head.

[0021] By adopting the above technical scheme, during testing, when the sealing needle presses against the charging nail mounting hole, the rubber sealing head at the end of the sealing needle is deformed by extrusion, so as to better block the charging nail mounting hole, so as to further ensure the accuracy of the test and the reliability of the test result.

Then, the lifting moving seat is controlled to move downward, so that the first positioning rod is pressed against the top of the internal component unit and is aligned with the key mounting hole. Next, the horizontal moving seat is controlled to move towards the positioning seat, so that the sealing needle presses against the side surface of the internal component unit and blocks the charging nail mounting hole. Finally, the air pipe is used to inflate the inside of the shell of the internal component unit through the first positioning rod, so as to test the air tightness. The test process is stable, and the test result can be ensured.

[0024] 2. Since the second component can move forward and backward relative to the first component, the first positioning rod can be adjusted left and right and up and down relative to the second component, so that the first positioning rod can be adjusted in the forward direction, the left direction and the upward direction during the actual installation of the first positioning rod, so that the first component can be aligned with the key mounting hole, and subsequent sealing and air filling tests can be performed;

[0025] 3.

[0035] Referring to Figure 2 A hair dryer sealing test device, comprising a test table 1, the test table 1 is L-shaped, and the inside is hollow. The test table 1 is provided with a positioning seat 2 for positioning and placing the internal assembly unit 100 to be tested, and the charging nail mounting hole 103 is right and the key mounting hole 102 is upward. The right side of the positioning seat 2 is provided with a horizontal moving seat 3, and the horizontal moving seat 3 can move left and right. The side of the horizontal moving seat 3 facing the positioning seat 2 is provided with a sealing needle 4, and the sealing needle 4 is aligned with the charging nail mounting hole 103. The upper side of the positioning seat 2 is provided with a lifting moving seat 5, and the lifting moving seat 5 can be lifted and controlled. The lifting moving seat 5 is provided with a first positioning rod 6, which is a hollow tube and is aligned with the key mounting hole 102.

[0036] During the test process, the internal assembly unit 100 to be tested is placed horizontally on the positioning seat 2, and the charging nail mounting hole 103 is right and the key mounting hole 102 is upward. Then, control the lifting moving seat 5 to move down, so that the first positioning rod 6 is pressed tightly on the top of the internal assembly unit 100 and is aligned with the key mounting hole 102. Then, control the horizontal moving seat 3 to move towards the positioning seat 2, so that the sealing needle 4 is pressed against the side of the internal assembly unit 100 and blocks the charging nail mounting hole 103. Finally, use the air pipe 200 to inflate the inside of the shell 101 of the internal assembly unit 100 through the first positioning rod 6 to test its air tightness. The test process is stable and can guarantee the test result.

[0037] In this embodiment, the horizontal moving seat 3 is driven and controlled by a gas cylinder, and the gas cylinder is hiddenly installed in the inside of the test table 1. Similarly, the lifting moving seat 5 is driven and controlled by a gas cylinder, and the gas cylinder is hiddenly installed in the inside of the test table 1. In other embodiments, the horizontal moving seat 3 and the lifting moving seat 5 can be driven and controlled by a linear motor or a motor with a lead screw.

[0038] Referring to Figure 3 In this embodiment, the lifting moving seat 5 includes a first part 51 and a second part 52, and the second part 52 is installed on the first part 51 through a third part 53.

[0039] Referring to Figure 3The first component 51 is arranged in a longitudinal horizontal direction, and one end of the first component 51 extends into the test table 1 and the other end extends out of the test table 1. The first component 51 is formed with a first slot 54 at the end extending out of the test table 1, and the first slot 54 extends in a longitudinal direction. One end of the third component 53 is fixedly connected to the second component 52, and the other end of the third component 53 extends upward to the bottom of the first slot 54 in the first component 51, and is fixedly locked in the first slot by a screw, so that the second component 52 can move forward and backward relative to the first component 51 through the third component 53.

[0040] The second component 52 is arranged in a transverse horizontal direction, and the second component 52 is formed with a second slot 55, and the second slot 55 extends in a transverse direction. The first positioning rod 6 is in the form of a hollow screw rod, and the first positioning rod 6 is installed in the second slot, and the upper and lower ends of the first positioning rod 6 are clamped and fixed to the second component 52 by nuts, so that the first positioning rod 6 can be adjusted left and right and up and down relative to the second component 52.

[0041] Since the second component 52 can move forward and backward relative to the first component 51, and the first positioning rod 6 can be adjusted left and right and up and down relative to the second component 52, during the actual installation of the first positioning rod 6, the first positioning rod 6 can be adjusted in the forward and backward direction, the left and right direction, and the up and down direction, so that the first component 51 can be aligned with the key mounting hole 102 for subsequent sealing and air charging tests.

[0042] Referring to Figure 3 In this embodiment, the second component 52 is also provided with a second positioning rod 7, which is arranged in parallel with the first positioning rod 6. The second positioning rod 7 is in the form of a screw rod, and is installed in the same way as the first positioning rod 6, i.e. in the second slot in the second component 52, and the upper and lower ends of the second positioning rod 7 are clamped and fixed to the second component 52 by nuts. Therefore, the second positioning rod 7 can also be adjusted left and right and up and down relative to the second component 52.

[0043] By arranging the second positioning rod 7, when the first positioning rod 6 is moved downward to press against the top of the internal component unit 100, the second positioning rod 7 is also pressed against the top of the internal component unit 100 at the same time, so as to further improve the positioning effect of the internal component unit 100, and prevent the internal component unit 100 from jumping vertically during the actual test, so as to ensure the stability and reliability of the test.

[0044] In this embodiment, a gasket is installed at the screw connecting the first component 51 and the third component 53, and at the nuts connecting the first positioning rod 6, the second positioning rod 7 and the second component 52, so as to further improve the installation stability.

[0046] By providing the rubber pad 8 at the bottom of the first positioning rod 6 and the second positioning rod 7, on the one hand, the shell 101 of the internal component unit 100 can be protected, so that the shell 101 of the first positioning rod 6 and the second positioning rod 7 is not easily damaged during the pressing process. On the other hand, after the second positioning rod 7 is pressed, the rubber pad 8 can seal the outer periphery of the button mounting hole 102 below it, so that it is not easy to leak during the subsequent inflation process, so as to ensure the test effect.

[0047] Reference Figure 4 In the embodiment, the end of the sealing needle 4 is provided with a rubber sealing head 9, which is made of silica gel material. During the test, when the sealing needle 4 presses against the charging pin mounting hole 103, the rubber sealing head 9 at the end is deformed by extrusion, so as to better block the charging pin mounting hole 103, so as to further ensure the accuracy of the test and the reliability of the test result.

[0048] The implementation principle is: during the test, the internal component unit 100 to be tested is placed horizontally on the positioning seat 2, and the charging pin mounting hole 103 faces right and the button mounting hole 102 faces up. Then, control the lifting moving seat 5 to move downward, so that the first positioning rod 6 is pressed tightly on the top of the internal component unit 100 and is aligned with the button mounting hole 102. Then, control the horizontal moving seat 3 to move towards the positioning seat 2, so that the sealing needle 4 presses against the side surface of the internal component unit 100 and blocks the charging pin mounting hole 103. Finally, the air pipe 200 is used to inflate the inside of the shell 101 of the internal component unit 100 through the first positioning rod 6, so as to test its air tightness. The test process is relatively stable, which can ensure the test result.

[0049] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
