The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Fig. 1 is a schematic structural view of an aerosol-generating device. The aerosol generating device in the figure comprises two parts, a cartridge 5 and an atomizer. Wherein, the atomizer includes mounting bracket 1 and cover and establish casing 3 above that.

Fig. 2 and 3 are schematic views of explosions in different directions of the aerosol-generating device. The control circuit 4 and the electrical connection assembly 2 of the aerosol generating device are both mounted on the mounting frame 1. Each electrical connection assembly 2 comprises an electrically conductive magnetic element 21 and an elastic electrical contact 22. The mounting 1 in the figures comprises opposite first and second connection ends 11, 15. The first connection end 11 is configured to be connected to the cartridge 5, and the second connection end 15 is configured to receive the charging plug when the charging plug charges the battery 62.

Fig. 4 is a schematic cross-sectional view of the atomizer. The region between the first connection end 11 and the positioning ring surface 33 is shown as a plug cavity 12 of the atomizer. Only one of the magnetic conductive members 21 is shown, and the outline of the convex portion 213 of the other magnetic conductive member 21 is shown with a thick broken line.

In the related art with publication number CN213961805U, the cartridge and the atomizer are connected to each other through a magnetic component and a conductive pin, so as to achieve the attraction and electrical connection of the cartridge and the atomizer (as shown in fig. 5B). In the process of loading the cartridge into the atomizer, the magnetic assembly is used for providing magnetic force for sucking the cartridge, the head of the conductive pin extends into the cavity from the middle area of the magnetic assembly, and the conductive pin can move in a telescopic way through the spring. When the contact of the cartridge is abutted on the magnetic component, the contact of the cartridge can be simultaneously abutted on the conductive pin, so that the cartridge moves in a direction away from the cavity. Thereby, an electrical connection of the atomizer with the cartridge is achieved. The above connection has the following defects:

firstly, the conductive pins, i.e. the pogo pins, need to be inserted into the magnetic assembly first in the assembly of the atomizer. In this process, the spring needle is not installed in place, so that the spring needle cannot be arranged along the axial direction of the cavity. The conductive pins in an inclined state may cause the atomizer to fail in use and testing. Meanwhile, after the spring pin head part and the magnetic component are installed, the tail part of the spring pin head part is welded with the control circuit. The problem of too high of the soldering points after the cold joint and the soldering is easy to occur in the process.

Secondly, when the magnetic component is fixed in the conductive groove by using glue, the situation of glue overflow can occur. When glue flows to the spring needle located at the middle position of the magnetic component, the resilience of the spring needle is affected, so that the spring needle cannot rebound normally. The yield of the atomizer is reduced. For this reason, it is necessary to further optimize the dispensing process, thereby increasing the manufacturing cost of the atomizer.

Thirdly, two components of the magnetic component and the conductive pins need to be arranged in the conductive groove at the same time, and the conductive groove needs to have enough width and thickness. Therefore, the interior of the atomizer needs to have a sufficient arrangement space. Meanwhile, the space of the groove part positioned between the two conductive grooves is occupied, and the monitoring of the atomizer on the entering air flow is affected.

Fourth, the contacts of the cartridge are in different contact with the magnetic assembly and the conductive pins. I.e. the magnetic assembly is in contact with the contact surface. In contrast, the conductive pins are in contact with the contact points. Therefore, the contact arrangement area needs to be large enough to meet the requirement of both abutting at the same time. At the same time, adequate leveling of the contact surface is also required. The processing difficulty of the contact shape is increased.

Fifth, the magnetic component is rigidly connected with the contact, and the conductive pins are elastically connected with the contact. When the cartridge is connected with the atomizer, the connection modes are required to be ensured to be in an effective state. For example, when the magnetic assembly is unable to effectively engage the contacts, the atomizer is unable to provide an effective force of engagement, nor is the cartridge able to effectively press against the conductive pins.

In some embodiments, as shown in fig. 1-4, the atomizer of the present example includes a housing 3, a mounting bracket 1, a plurality of electrically conductive magnetic members 21, a plurality of resilient electrical contacts 22, and a control circuit 4. The housing 3 has a first socket 31. The mounting frame 1 comprises a first connecting end 11, the first connecting end 11 is provided with a plurality of mounting grooves 111, and connecting holes 112 are formed in the bottoms of the mounting grooves 111. The shell 3 is sleeved on the first connecting end 11, and the first jack 31, the first connecting end 11 and the inner wall of the shell 3 between the first jack 31 and the first connecting end 11 form a plug cavity 12. The plurality of conductive magnetic members 21 are installed in the plurality of installation grooves 111 in one-to-one correspondence and elastically connected to the plurality of elastic electrical contacts 22 through the connection holes 112 in one-to-one correspondence. The control circuit 4 includes a plurality of feeding points 41, and the plurality of elastic electrical contacts 22 are electrically connected to the plurality of feeding points 41, respectively.

When the cartridge 5 is mounted in the socket 12, the contacts 51 of the cartridge 5 in this embodiment are attracted to and electrically connected to the plurality of conductive magnetic members 21, respectively, in a one-to-one correspondence. Thereby achieving a mechanical and electrical connection of the cartridge 5 to the atomizer.

In other words, the first connection end 11 is disposed in the housing 3 in a penetrating manner and forms an insertion cavity 12 with the inner wall of the housing 3, the first socket 31 is located on a side of the insertion cavity 12 away from the first connection end 11, the first connection end 11 is provided with a plurality of mounting slots 111, the mounting slots 111 face the first socket 31, and the bottom is provided with a connection hole 112. Each pair of electrical connection assemblies 2 comprises an electrically conductive magnetic member 21 and an elastic electrical contact 22, and the electrically conductive magnetic members 21 of the plurality of pairs of electrical connection assemblies 2 are mounted in the plurality of mounting grooves 111 in a one-to-one correspondence manner and are elastically connected with the elastic electrical contact 22 through the connection holes 112.

In this embodiment, the cartridge 5 and the atomizer are rigidly connected to each other during loading of the cartridge 5. I.e. the electrical connection assembly 2 is in a stationary state relative to the housing 3 during loading of the cartridge 5. Thus, during long-term use of the aerosol-generating device, the user constantly replaces the cartridges. The atomizer can remain in the long-term repeated replacement of the cartridge 5, the mechanical mechanism being sufficiently stable.

Alternatively, the conductive magnetic member 21 may be fixed in the mounting groove 111 with glue. To ensure that the conductive magnetic member 21 does not easily escape from the mounting groove 111. Alternatively, the conductive magnetic member 21 and the mounting groove 111 may be configured as an interference fit, i.e., the outer diameter of the conductive magnetic member 21 is slightly larger than the diameter of the mounting groove 111. When the conductive magnetic member 21 is placed in the mounting groove 111, the conductive magnetic member 21 is prevented from coming out of the mounting groove 111.

It will be readily appreciated that dust or dirt may enter the socket cavity 12 from the first socket 31 when the user of the atomizer is more frequent in changing the cartridge 5 or when the aerosol generating device is used in a more hostile environment. At the same time, the cartridge 5 will also leak oil during use,

the above-mentioned fixing manner of the conductive magnetic member 21 and the mounting groove 111 can make the plug cavity 12 and other positions in the atomizer be in a mutually isolated state (as shown in the region i and the region ii in fig. 4). And further can avoid dirt from entering into the region II from the plug-in cavity 12, influencing the normal use of the atomizer. The influence of dirt on the telescoping movement of the spring needle in the related technology can be well avoided.

In summary, the atomizer of the embodiment of the present utility model utilizes the conductive magnetic member 21 and the elastic electric contact 22 provided in pairs, and the conductive magnetic member 21 is provided closer to the first socket 31 with respect to the elastic electric contact 22. Thus, on the one hand, during the assembly stage of the atomizer, the elastic electrical contact 22 may be mounted on the control circuit 4 first, and then, when the control circuit 4 is assembled with the mounting frame 1, the assembly of the atomizer may be quickly realized by using the elastic connection between the elastic electrical contact 22 and the conductive magnetic member 21. In the stage of assembling the cartridge 5 and the atomizer, the cartridge 5 is fixed in the plug-in cavity 12 by utilizing the magnetic force of the conductive magnetic piece 21, so that the cartridge 5 can be mechanically connected with the atomizer stably. Meanwhile, the electric connection can be realized through the mutual abutting positions of the two. Especially under the condition of the internal space of the atomizer, the structure and the number of parts in the atomizer are simplified, and the yield of the atomizer is improved. On the other hand, the contact area with the contacts 51 of the cartridge 5 is reduced by the electrical connection assembly 2, so that the contact 51 area can be smaller, thereby leaving more layout space for the air holes thereon.

Specifically, the number of the electrical connection assemblies 2 is 2. In contrast, the number of contacts on the cartridge 5 is also two. The battery 62 in the atomizer supplies dc power to the cartridge 5 via the 2 electrical connection assemblies 2 to cause the cartridge 5 to generate aerosol. The outer contour of the radial cross section of the atomizer is substantially elliptical. The 2 electric connection components 2 are arranged at intervals along the major axis direction of the ellipse.

Further, the conductive magnetic member 21 includes a magnetic body and a conductive coating layer, and the magnetic body is coated with the conductive coating layer. The magnetic body and the conductive coating in this embodiment provide an attracting action and a conductive action, respectively. The magnetic body has magnetism, and when the cartridge 5 is loaded into the insertion cavity 12, the cartridge 5 is attracted. The size of the volume of the magnetic body can be configured by a person skilled in the art to vary the attraction force of the conductive magnetic member 21. The thickness of the conductive coating can also be configured by those skilled in the art to vary the conductive properties of the conductive magnetic element 21 to current.

Preferably, the magnetic body is a permanent magnetic material including, but not limited to, neodymium iron boron or alnico. The conductive coating layer material includes but is not limited to gold or copper. For example, a magnetic body having a shape corresponding to the mounting groove 111 is formed by sintering a neodymium iron boron material, and then nickel is plated on the magnetic body by an electroplating process, and then gold is plated on the nickel layer. Thereby ensuring that the conductive magnetic piece 21 has conductivity and ensuring that the conductive magnetic piece 21 has certain corrosion resistance.

In some embodiments, as shown in fig. 1-4, the conductive magnetic element 21 includes a protrusion 213 and a contact surface 214 facing away from each other, the contact surface 214 corresponding to the connection hole 112.

The enlarged view in fig. 2 shows a specific form of the protrusion 213 and the contact surface 214, the contact surface 214 facing the bottom of the mounting groove 111 and at least partially corresponding to the connection hole 112. The protruding portion 213 is a round package structure and is located at the center of the end surface of the conductive magnetic member 21. The present embodiment can bring the contact 51 of the cartridge 5 into point contact with the conductive magnetic member 21 by the convex portion 213. That is, the contact 51 is attracted and fed by the contact convex portion 213. In this form, the area of the contact 51 may be correspondingly reduced, for example, the contact 51 may be configured to be slightly larger than the top region of the dome structure.

In contrast, the contact surface 214 is a flat surface, and after the elastic electrical contact 22 is mounted on the mounting frame 1, the elastic electrical contact 22 can be synchronously abutted on the flat surface by the elastic piece 221. Thus, the contact surface 214 is provided as a flat surface, which facilitates the interconnection of the elastic electrical contact 22 with the conductive magnetic member 21. The occurrence of the situation that the elastic electric contact 22 and the conductive magnetic element 21 are mutually staggered after the control circuit 4 is installed is reduced or even avoided.

In some embodiments, as shown in fig. 1-4, the conductive magnetic element 21 includes a cylindrical body 215, a side surface of the cylindrical body 215 is a cylindrical surface, one end surface of the cylindrical body 215 forms a contact surface 214, and the protruding portion 213 is protruding from the other end surface of the cylindrical body 215. The column 215 can be used for mutual positioning between the conductive magnetic element 21 and the mounting groove 111.

Further, the shape of the mounting groove 111 is adapted to the columnar body 215, the columnar body 215 is mounted to the mounting groove 111, and the plurality of protruding portions 213 are located outside the mounting groove 111 and at the same distance from the first socket 31 (as indicated by a broken line iii in fig. 4).

The side surfaces and the bottom surfaces of the columnar bodies 215 in the present embodiment are respectively in contact with the side surfaces and the bottom surfaces of the mounting grooves 111 to realize positioning of the mounting grooves 111 on the conductive magnetic members 21. And a chamfer may be provided at a connection position of the side surface and the end surface of the columnar body 215 to facilitate assembly of the conductive magnetic member 21. The same distance between the plurality of protruding portions 213 and the first socket 31 ensures that the plurality of protruding portions 213 can be electrically connected to the cartridge 5 at the same time when the cartridge 5 is mounted in the socket 12.

In some embodiments, as shown in fig. 1-4, the first connection end 11 is provided with a first side 113, the first side 113 faces the first socket 31, the first side 113 is recessed away from the first socket 31 to form a mounting groove 111, the side of the mounting groove 111 includes at least one cylindrical side wall 114, the bottom surface of the mounting groove 111 is an annular surface 115, and the annular surface 115 surrounds the connection hole. The conductive magnetic member 21 is mounted in the mounting groove 111, and the bottom edge of the conductive magnetic member 21 abuts against the annular surface 115.

The present embodiment may define the distance of the conductive magnetic element 21 in the axial direction of the socket 12 by the annular surface 115. So that it can be stably mounted in the mounting groove 111. The annular surface 115 may also carry the force of the cartridge 5 against the atomizer when the cartridge 5 is loaded into the socket 12.

In some embodiments, as shown in fig. 1-4, at least one cylindrical sidewall 114 is two cylindrical sidewalls 114, the diameter of the cylindrical sidewall 114 proximate the first socket 31 being greater than the diameter of the cylindrical sidewall 114 distal the first socket 31.

It is easy to understand that, in order to facilitate fixing the conductive magnetic member 21 in the mounting groove 111, glue may be applied to the inner side of the mounting groove 111 or the conductive magnetic member 21. However, during the process of mounting the conductive magnetic member 21 in the mounting groove 111, glue overflow occurs. I.e. glue will spill over the top of the mounting groove 111.

The cylindrical side wall 114 on the side away from the connection hole 112 in this embodiment can play a guiding role in the mounting process of the conductive magnetic member 21. Meanwhile, when the glue overflows, the device can be used for accommodating the glue. Alternatively, in order to improve the connection performance between the conductive magnetic element 21 and the mounting groove 111, the glue may be mainly applied to the cylindrical sidewall 114 on the side away from the connection hole 112. Thereby, the conductive magnetic element 21 is positioned radially by the cylindrical side wall 114 close to the connection hole 112, and the conductive magnetic element 21 is fixed and the socket 12 is spaced from the atomizer rear side region by the glue of the cylindrical side wall 114 far from the connection hole 112.

In some embodiments, as shown in fig. 1-4, the atomizer further includes a flow sensor 61. The flow sensor 61 is communicatively connected to the control circuit 4. The mounting frame 1 is also provided with a sensor receiving groove 13. The first connecting end 11 comprises a partition plate 116, the partition plate 116 and the first side 113 are respectively located at two sides of the first connecting end 11, the connecting hole 112 is formed in the partition plate 116, the first connecting end 11 is provided with an air passage 117, and the air passage 117 penetrates through the first connecting end 11. The sensor receiving groove 13 is adjacent to the partition plate 116 and is communicated with the plug-in cavity 12 through an air passage 117, and the control circuit 4 is positioned on the side of the partition plate 116 away from the first side 113. The flow sensor 61 is mounted to the sensor housing groove 13. The sensing head of the flow sensor 61 described above may be configured to extend into the airway 117.

The present embodiment monitors the amount of air currently being inhaled by the user through the flow sensor 61, and when the amount of air is too large or too small, the aerosol of the aerosol generating device is correspondingly adjusted. The partition plate 116 serves to space the plug-in chamber 12 from the rear region of the atomizer.

Further, the mounting bracket 1 further includes a plurality of circuit board mounting holes 14, and the plurality of circuit board mounting holes 14 are adjacent to and face the sensor accommodating groove 13. The control circuit 4 is fixedly connected with the mounting frame 1 through a circuit board mounting hole 14, and a partial area of the control circuit 4 corresponds to the sensor accommodating groove 13. The circuit board mounting holes 14 are matched with the control circuit 4, so that the control circuit 4 can be stably and fixedly connected with the mounting frame 1.

The control circuit 4 is arranged at the mounting position of the mounting frame 1, the substrate 42 is positioned above the sensor accommodating groove 13, and the surface of the substrate 42 is perpendicular to the direction of the sensor accommodating groove 13. The elastic electrical contact 22 includes a cover 222 and an elastic piece 221, and each feeding point 41 is disposed at the same side edge of the substrate 42. The elastic electrical contact 22 is disposed at the mounting position of the control circuit 4, the cover 222 is electrically connected to the feeding point 41, and the elastic piece 221 in a free state extends into the connection hole 112.

The enlarged right-hand side of fig. 2 shows a specific form of the resilient electrical contact 22, the cover 222 and the resilient tab 221 each being of an electrically conductive configuration, wherein one end of the resilient tab 221 is connected to the cover 222 and the other end is elastically deformable relative to the cover 222. When the elastic electrical contact 22 is electrically connected to the feeding point 41, the cover 222 can be soldered at a corresponding position of the substrate 42, and compared with the connection between the conductive wire and the feeding point 41, the bottom surface of the cover 222 in this embodiment has a larger area, so that the two parts are not easy to be shorted. The elastic electric contact 22 as a conductive member connected between the conductive magnetic member 21 and the feeding point 41, the connection of the cover 222 and the feeding point 41, and the connection of the elastic piece 221 and the conductive magnetic member 21 can be performed independently of each other, so that the mutual influence is smaller and interference does not occur. Meanwhile, the elastic piece 221 is configured to extend into the connection hole 112, so that mutual abutment of the elastic piece 221 and the contact surface 214 can be well achieved.

Specifically, the number of the circuit board mounting holes 14 is 2, and are located on both sides of the sensor housing groove 13, respectively. The front surface of the substrate 42 faces the bottom of the sensor accommodation groove 13 and is erected above the sensor accommodation groove 13. Thereby, the electrical connection of the flow sensor 61 and the control circuit 4 is facilitated.

In some embodiments, as shown in fig. 1-4, the housing 3 includes a locating annulus 33, the locating annulus 33 surrounding the first socket 31. The cartridge 5 is in the mounted state in the socket 12, and the mating surface 52 of the cartridge 5 abuts against the positioning annular surface 33. Wherein the mating surface 52 is at a predetermined distance from the contacts 51 of the cartridge 5. The mating surface 52 of this embodiment, together with the contact 51, limits the insertion depth of the cartridge 5 so that no significant gaps appear in the aerosol generating device's appearance, which is more aesthetically pleasing.

In some embodiments, as shown in fig. 1-4, the housing 3 is provided with an air intake aperture 34. The first connecting end 11 is provided with an air groove 118 and a flange 119, the air groove 118 is positioned among the plurality of mounting grooves 111, the flange 119 simultaneously surrounds the mounting grooves 111 and the air groove 118, the flange 119 is provided with a notch 1191, and the air groove 118 is communicated with the air inlet hole 34 through the notch 1191. The mounting bracket 1 is in a mounted position within the housing 3 with the air inlet aperture 34 located between the first socket 31 and the first connection end 11 and adjacent the mounting slot 111.

It will be readily appreciated that when a user uses the aerosol generating device, inhaled gas may flow into the cartridge 5 through the inlet aperture 34, the indentations 1191 and the air reservoir 118 of the present embodiment (as indicated by the 3 arrows in figure 4). The size of the air inlet holes 34 and the notches 1191 and the volume and position of the air tank 118 directly affect the resistance of the user to inhale the aerosol, thereby affecting the taste of the user. Resistance, i.e. the pressure at which air is forced through the whole cigarette.

In fig. 4, the air groove 118 and the two mounting grooves 111 are arranged on the first side 113. Therefore, the width and depth of the mounting groove 111 may have an influence on the suction resistance. A mounting boss 211 is further provided near the notch 1191, the mounting boss 211 is provided protruding at the bottom of the air tank 118, and the air passage 117 penetrates through both the mounting boss 211 and the partition plate 116. The conductive magnetic member 21 in the above embodiment can reduce the occupation of the internal space of the atomizer. Thus, the configuration and location of the air channel 118, mounting boss 211, and indentation 1191 are more readily arranged by those skilled in the art. For example, to increase the resistance to suction, the size of the notch 1191 may be reduced. For another example, to facilitate securing the sensing head of the flow sensor 61, the diameter of the air passage 117 may be increased, thereby increasing the outer diameter of the mounting boss 211.

Fig. 5 is a schematic view of the structure of the conductive magnetic member 21 in various embodiments. Together, three conductive magnetic elements 21 are shown, namely state IVa, state IVb and state IVc, the sides of the three conductive magnetic elements 21 being generally cylindrical. The shape of the magnetic conductive member 21 in the state iva is similar to that of the magnetic conductive member 21 in the enlarged view of fig. 2. The diameter dimension and the length dimension of the column 215 are similar. The conductive magnetic element 21 in state ivc is entirely a short shank structure 219 having a smaller diameter dimension than the length dimension. The conductive magnetic element 21 in state ivb includes a pie-shaped structure 217 and a round pack protruding from the pie-shaped structure 217. The radial dimension of the pie structure 217 is smaller than its thickness dimension.

In some embodiments, as shown in state ivb of fig. 1-4 and 5, the conductive magnetic element 21 includes a pie-shaped structure 217 and a round pack 218 protruding above the pie-shaped structure 217. The shape of the mounting slot 111 is adapted to the cookie shaped structure 217. When the conductive magnetic member 21 is mounted in the mounting groove 111, the cookie shaped structure 217 is positioned in the mounting groove 111 and the round pack 218 protrudes from the mounting groove 111.

In the case where the axial length of the housing 3 is fixed, the conductive magnetic member 21 configured in this embodiment can reduce the length of the mount 1 as compared with the conductive magnetic member 21 shown in the state iva in fig. 5. As shown by the dashed line VI in FIG. 5, the inlet holes 34 in state IVb are further from the locating annulus 33. Thus, the cartridge 5 is made to be inserted into the atomizer to a larger volume, and more aerosol substrate can be accommodated in the cartridge 5.

In some embodiments, as shown in state ivc of fig. 1-4 and 5, the electrically conductive magnetic element 21 is a short handle structure 219. The shape of the mounting groove 111 is adapted to the short shank structure 219. When the conductive magnetic member 21 is mounted in the mounting groove 111, one end of the short shank structure 219 protrudes from the mounting groove 111.

The conductive magnetic member 21 of the present embodiment does not need to be provided with the protruding portion 213, and can be connected to the contact 51 by the end surface of the short shank structure 219. That is, the end face of the stub shank structure 219 is sized to conform to the shape of the contact 51. At the same time, the radial dimension of the short shank structure 219 is smaller than the conductive magnetic element 21 in state IVa. Thus, the radial dimension of the atomizer can be made smaller (as indicated by the broken line V in FIG. 5) or a larger arrangement space can be provided for the air tank 118.

Fig. 6 is a schematic structural view of the elastic electrical contact 22 of the present embodiment.

In some embodiments, as shown in fig. 6, the resilient electrical contact 22 includes a cover 222 and a resilient tab 221. The cover 222 includes a top sheet 2221, a bottom sheet 2222, two side sheets 2223 and a baffle 2224, where the top sheet 2221, the bottom sheet 2222 and the two side sheets 2223 surround to form a containing cavity 2225, and the baffle 2224 is disposed at an edge of the side sheet 2223 and is bent toward a port of the containing cavity 2225. The elastic sheet 221 includes a connection end 2211, a stop end 2212, and a plurality of curved segments 2213 between the connection end 2211 and the stop end 2212, the connection end 2211 being connected to the bottom sheet 2222. Meanwhile, the elastic piece 221 is in a free state, a bending section 2213 adjacent to the stop end 2212 is bent to the outside of the port of the accommodating cavity 2225, and the stop end 2212 extends into the accommodating cavity 2225 and is engaged with the stop piece 2224.

Specifically, the elastic sheet 221 includes three curved segments 2213 connected in sequence. Wherein two curved segments 2213 near the connection end 2211 are located in the receiving cavity 2225. A curved section 2213 adjacent the stop end 2212 extends from the interior of the receiving cavity 2225.

It is easy to understand that the elastic sheet 221 in the present embodiment may be elastically deformed, and when the elastic sheet 221 is not compressed, the three curved sections 2213 may be extendedly deformed, so that the curved sections 2213 located outside the receiving cavity 2225 protrude to the outside. In this form, the stop end 2212 is engaged with the stop piece 2224, so as to limit the movement range of the elastic piece 221, so as to prevent the transition deformation thereof. At the same time, the two curved segments 2213 located inside the receiving cavity 2225 will remain spaced from the top sheet 2221 and the bottom sheet 2222, i.e. not in contact with the cover 222. As shown by arrows a1, a2 and a3 in fig. 6, when the elastic sheet 221 is compressed, the two curved sections 2213 located inside the receiving chamber 2225 move in the directions of the top sheet 2221 and the bottom sheet 2222, respectively. That is, when the compression amount is within a certain range, the elastic force generated by the elastic piece 221 is small. When the compression amount is excessively large, the two curved sections 2213 located inside the receiving cavity 2225 are pressed by the top sheet 2221 and the bottom sheet 2222, so that the elastic force generated by the elastic sheet 221 is greatly increased. So as to prevent the elastic sheet 221 from being deformed by transition, so that it cannot be restored to the original shape after the pressure is lost.

Preferably, the stop end 2212 comprises two wing plates protruding to both sides of the elastic sheet 221. In contrast, the number of the baffle 2224 is two and is provided on the two side pieces 2223, respectively. Thus, the two wing plates are engaged with the two blocking pieces 2224, respectively, so that the blocking end 2212 can be stably limited in the accommodating cavity 2225.

In some embodiments, as shown in fig. 3, the contact surface 214 is recessed with a recess 216 corresponding to the connection location of the resilient electrical contact 22, the recess 216 being configured for resilient connection and positioning of the resilient electrical contact 22.

In contrast, as shown in fig. 6, the curved section 2213 located outside the housing cavity 2225 is provided with a projection 2214 facing the outside of the housing cavity 2225. The protrusion 2214 may be formed by stamping or the like. The protrusion 2214 may snap into engagement with the recess 216 when the resilient electrical contact 22 is connected to the electrically conductive magnetic member 21. Thereby, a stable connection of the elastic electrical contact 22 with the conductive magnetic element 21 is ensured.
