Description

Technical Field

[0001] The utility model relates to the technical field of electric stimulators, in particular to a household electric stimulator. Background Art

[0002] An electrical stimulator can stimulate some of the weaker nerves and muscles in the human body through weak electric currents, assisting in controlling the normal activity of the corresponding nerves and muscles, allowing people to perform muscle activity normally when the neuromuscular function is reduced or lost. A large number of electrical stimulators are used in hospitals and are large in size, making them unsuitable for home use.

[0003] However, the home-use electrical stimulators currently on the market do not take the safety of use into full consideration. Due to the high instantaneous voltage during normal operation, the voltage control components of the circuit have high requirements when in use. In daily household use, they are often used while charging, which will undoubtedly increase the requirements for circuit safety and cause certain safety hazards in daily use.

[0004] Therefore, how to prevent users from using the device while charging it in daily household use is a problem that needs to be solved urgently. Utility Model Content

[0013] Preferably, the central axis of the charging port and the moving trajectory of the switch control rod are on the same straight line.

[0014] Furthermore, the bottom wall of the sliding slot is provided with a limit block and a first through hole for the switch control rod to pass through, the switch control rod can move in the first through hole, and the limit block is located between the first through hole and the second end of the sliding slot;

[0015] A click buckle is also provided on the inner side of the sliding switch key, and the click buckle is provided with a receiving groove with an opening. When the sliding switch key is installed in the sliding groove and the sliding switch key slides toward the second end of the sliding groove, the limit block passes through the opening and enters the receiving groove.

[0016] Preferably, the limit block is a diamond-shaped block, and a diagonal line of the diamond-shaped block is on the same straight line as the moving track of the switch control rod;

[0017] The shape of the click buckle is "concave", and oppositely arranged protrusions are provided on both sides of the opening. The protrusions face the central axis of the opening, and the diameter of the opening is less than or equal to the length of the other diagonal line in the diamond block, so that the click buckle and the limit block have an interference fit.

[0018] Furthermore, the lengths of the two diagonals of the diamond block are not equal, and the longer diagonal of the diamond block is on the same straight line as the moving trajectory of the switch control rod, wherein the angle close to the first via hole is smaller than the angle away from the first via hole, and the diameter of the opening is less than or equal to the length of the shorter diagonal of the diamond block.

Since the charging port is located on the extension line of the moving track of the switch lever, and the first end of the sliding groove is connected with the charging slot and partially overlaps, the first end of the sliding switch key is located in the charging slot and covers the charging port to avoid charging when the power is on. If the charging port is arranged horizontally and the width of the sliding switch key is greater than the length of the charging port, the charging port can be completely covered. If the charging port is arranged vertically, the sliding switch key can partially cover the charging port. When the electrical stimulator body is powered off, the first end of the sliding switch key is separated from the charging slot, so that the second end of the sliding switch key abuts against the side wall of the sliding slot, avoiding the entire charging slot, which is convenient for charging.

[0027] Through the position design of the charging slot and the sliding slot, and the sliding switch can enter the charging slot when powered on and can partially or completely cover the charging port, the situation of charging while in use is avoided. At the same time, the inability to charge while in use can reduce the requirements of various voltage control components on the circuit board, which not only ensures safety during use, but also reduces the cost of the electric stimulator.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Embodiment 1

[0040] Please refer to Figures 1 to 4 , is a household electrical stimulation device provided by an embodiment of the utility model, the electrical stimulation device 100 comprises:

[0041] The electrical stimulator body 10 is provided with a circuit board (not shown in the figure) and a switch device (not shown in the figure) electrically connected to the circuit board. A switch lever 30 is provided on the side of the switch device and can be translated relative to the switch device.

[0042] A charging slot 11 is provided on the side wall of the electrical stimulator body 10, and a charging port 111 for electrically connecting to the circuit board is provided in the charging slot 11. The charging port 111 is located in the extension direction of the moving track of the switch control rod 30;

[0043] The sliding switch key 20 has a lever locking groove 22 on its inner side that cooperates with the switch lever 30, so that the sliding switch key 20 and the switch lever 30 move synchronously; and

[0044] The sliding groove 12 is arranged on the side wall of the electrical stimulator body 10, and the first end of the sliding groove 12 is connected with the charging groove 11 and partially overlaps. The sliding switch key 20 is slidably connected with the sliding groove 12. When the first end of the sliding switch key 20 slides to abut against the first end side wall of the sliding groove 12, the electrical stimulator body 10 is powered on, and the first end of the sliding switch key 20 is located in the charging groove 11 and covers the charging port 111, or when the second end of the sliding switch key 20 slides to abut against the second end side wall of the sliding groove 12, the electrical stimulator body 10 is powered off, and the first end of the sliding switch key 20 is separated from the charging groove 11. Specifically, a switch control rod 30 is provided on the side of the switch device, and the switch control rod 30 extends away from the electrical stimulator body 10. The sliding switch key 20 is slidably connected with the electrical stimulator body 10, and the sliding switch key 20 cover is arranged above the sliding groove 12 and is engaged with the switch control rod 30.

[0045] Specifically, a first through hole 121 may be formed on the bottom wall of the sliding groove 12 , so that one end of the switch lever 30 passes through the first through hole 121 and is engaged with the lever locking groove 22 .

[0046] In this embodiment, the electrical stimulator body 10 is placed vertically, and after the switch device is installed, the movement trajectory of the switch control rod 30 is up and down translation.

[0047] In this embodiment, the electrical stimulator body 10 also includes a charging device (not shown in the figure) for supplying power to the circuit board, and the switch device is arranged in parallel with the charging device, and the switch device is located above the charging device. Based on the switch device being located above the charging device, the sliding slot 12 is arranged at the position of the electrical stimulator body 10 corresponding to the switch device, and the charging slot 11 is arranged at the position of the electrical stimulator body 10 corresponding to the charging device, so the sliding slot 12 is also located above the charging slot 11.

[0048] Specifically, the size of the charging slot 11 is adapted to the output interface of the charging adapter, and the charging port 111 is located on the bottom wall of the charging slot 11 and is used to electrically connect the output interface of the charging adapter to the circuit board.

[0049] Specifically, the sliding switch key 20 is located in the charging slot 11 and covers the charging port 111 in two cases: one is to enter the charging slot 11 and completely cover the charging port 111, and the other is to enter the charging slot 11 and partially cover the charging port 111. Figure 4 As shown, in this embodiment, the second method is used to partially cover the charging port 111 to remind the user that they cannot use the device while charging, and to restrict the user from using the device while charging.

[0050] In this embodiment, the electrical stimulator body 10 manually applies a thrust to push the sliding switch key 20 to move up and down. Since one end of the switch lever 30 is engaged with the lever clamping groove 22, the sliding switch key 20 is slidably connected with the sliding groove 12, so that the sliding switch key 20 slides and drives the switch lever 30 to move up and down synchronously. The upward movement of the switch lever 30 cuts off the power supply of the circuit board of the electrical stimulator body 10, and the downward movement of the switch lever 30 powers on the circuit board of the electrical stimulator body 10. In other embodiments, the electrical stimulator body 10 can move up and down by electrically controlling the switch lever 30, and the upward and downward movement of the switch lever 30 drives the sliding switch key 20 to move up and down synchronously, which will not be described in detail here.

[0051] The charging port 111 is located on the extension line of the moving track of the switch lever 30, and the first end of the sliding slot 12 is connected with the charging slot 11 and partially overlaps. Therefore, when the power is turned on, the first end of the sliding switch key 20 abuts against the first end side wall of the sliding slot 12. Figure 4 As shown, the first end of the sliding switch key 20 is located in the charging slot 11 and covers the charging port 111 to avoid charging when powered on. If the charging port 111 is arranged horizontally and the width of the sliding switch key 20 is greater than the length of the charging port 111, the charging port 111 can be completely covered. If the charging port 111 is arranged vertically, the sliding switch key 20 can partially cover the charging port 111. When the electrical stimulator body 10 is powered off, the first end of the sliding switch key 20 is disengaged from the charging slot 11, so that the second end of the sliding switch key 20 abuts against the second end side wall of the sliding slot 12, as shown in FIG. Figure 3 As shown, the entire charging slot 11 is avoided to facilitate charging.

[0052] By designing the positions of the charging slot 11 and the sliding slot 12, and the sliding switch 20 can enter the charging slot 11 and partially or completely cover the charging port 111 when powered on, the situation of charging while in use can be avoided. At the same time, the requirement for each voltage control component on the circuit board can be reduced when charging while in use is not possible, which not only ensures the safety during use, but also reduces the cost of the electrical stimulator 100.

[0053] Embodiment 2

[0054] Please refer to Figures 1 to 4 , based on the first embodiment, the moving track of the switch lever 30 of the utility model is parallel to the length direction of the electrical stimulator body 10;

[0055] The charging port 111 is a through hole in an elongated shape, and the extending direction of the charging port 111 is parallel to the moving track of the switch lever 30 .

[0056] In this embodiment, the shape of the electrical stimulator body 10 is roughly a rectangular parallelepiped, the electrical stimulator body 10 is placed vertically, and the extension direction of the switch control rod 30 extends away from the electrical stimulator body 10 and extends out of the surface of the electrical stimulator body 10. Preferably, the movement trajectory of the switch control rod 30 is parallel to the length direction of the electrical stimulator body 10, and the power is turned on and off by sliding the switch key 20 without changing the thickness of the electrical stimulator body 10.

[0057] In this embodiment, the output interface of the charging adapter is generally a Type-C interface, and therefore, the shape of the charging port 111 is adapted to the output interface of the charging adapter, and is a slender through hole.

[0058] Preferably, the central axis of the charging port 111 is in the same straight line as the moving trajectory of the switch lever 30 , so that the sliding switch key 20 can cover the charging port 111 when entering the charging slot 11 .

[0059] In a specific embodiment, the electrical stimulator body 10 is placed vertically, the sliding slot 12 and the charging slot 11 are located on the left side wall of the electrical stimulator body 10, the sliding slot 12 is connected to the charging slot 11 and partially overlaps, the movement trajectory of the switch control rod 30 is up and down translation, the charging port 111 is vertically arranged, one end of the charging port 111 is close to the overlapping part formed by the sliding slot 12 and the charging slot 11, and the central axis of the charging port 111 is on the same straight line as the movement trajectory of the switch control rod 30. When the sliding switch key 20 moves down until it abuts against the side wall of the sliding slot 12, the sliding switch key 20 can partially cover one end of the charging port 111, so that the charging adapter cannot be inserted into the charging port 111. In this way, the user is prevented from using the electrical stimulator while charging.

[0060] Embodiment 3

[0061] Please refer to Figure 5 and Figure 6 On the basis of the first and second embodiments, the bottom wall of the sliding slot 12 of the utility model is provided with a limit block 123 and a first through hole 121 for the switch control rod 30 to pass through, the switch control rod 30 can move in the first through hole 121, and the limit block 123 is located between the first through hole 121 and the second end of the sliding slot 12;

[0062] A click buckle 21 is also provided on the inner side of the sliding switch key 20. The click buckle 21 is provided with a receiving groove 211 having an opening 212. When the sliding switch key 20 is installed in the sliding groove 12 and the sliding switch key 20 slides toward the second end of the sliding groove 12, the limit block 123 passes through the opening 212 and enters the receiving groove 211.

[0063] Specifically, the central axis of the limit block 123 is parallel to the moving track of the switch lever 30 , the opening 212 is opened toward the limit block 123 , and the central axis of the opening 212 is on the same straight line as the central axis of the limit block 123 .

[0064] Specifically, the first via hole 121 is a thin and long strip-shaped via hole, and the extension direction of the first via hole 121 is up and down. The cross-sectional shape of the first via hole 121 can be a rectangle or a rounded rectangle.

[0065] In a specific embodiment, when the sliding switch key 20 moves upward, the click buckle 21 provided on the inner side of the sliding switch key 20 moves toward the limit block 123, so that the limit block 123 passes through the opening 212 and enters the receiving groove 211. When the sliding switch key 20 moves upward to abut against the side wall of the sliding groove 12, the click buckle 21 completely enters the receiving groove 211, thereby cutting off the power and avoiding the charging slot 11.

[0066] In this embodiment, the click buckle design in the sliding switch key provides a good hand feel and operation feedback, so that the user can clearly feel the change of the switch state during the operation, thereby increasing the convenience of use.

[0067] Embodiment 4

[0068] Please refer to Figures 5 to 8 On the basis of the first, second and third embodiments, the limit block 123 of the utility model is a diamond block, and a diagonal line in the diamond block is on the same straight line as the moving track of the switch control rod 30;

[0069] The shape of the click buckle 21 is "concave", and oppositely arranged protrusions are provided on both sides of the opening 212, and the protrusions face the central axis of the opening 212. The diameter of the opening 212 is less than or equal to the length of the other diagonal line in the diamond block, so that the click buckle 21 and the limit block 123 have an interference fit.

[0070] In this embodiment, one diagonal line of the diamond block is on the same straight line as the moving track of the switch control rod 30, that is, when the switch control rod 30 moves up and down, one diagonal line of the diamond block is vertically arranged, and the other diagonal line is horizontally arranged.

[0071] Specifically, the protrusion is arranged toward the central axis of the opening 212, which reduces the inner diameter of the opening 212 and is used to match the length of the horizontally arranged diagonal of the diamond block, so that the diameter of the opening 212 is less than or equal to the length of the horizontally arranged diagonal, thereby achieving an interference fit.

[0072] Due to the interference fit between the click buckle 21 and the limit block 123, when the limit block 123 is inserted into the receiving groove 211, the user needs to exert a certain force to completely insert it into the receiving groove 211; after the click buckle 21 is completely inserted into the receiving groove 211, the sliding switch key 20 will not automatically return to its original position due to the action of the limit block 123, and it also needs to exert a certain force to disengage it from the click buckle 21. At the same time, the interference fit can prevent the user from accidentally touching the electrical stimulator to power on.

[0073] Preferably, the protrusion is provided with a first guide surface and a second guide surface, and the first guide surface and the second guide surface can be inclined surfaces. Specifically, a first inclined surface for the limit block 123 to slide into the receiving groove 211 can be provided on both outer sides of the protrusion, and the first inclined surface is inclined downward from the outer edge of the outer side to the center of the opening 212, and a second inclined surface for the limit block 123 to slide out of the receiving groove 211 is provided on both inner sides of the protrusion, and the second inclined surface is inclined upward from the inner edge of the inner side to the center of the opening 212. By providing the first inclined surface and the second inclined surface, the limit block 123 is guided, so that the limit block 123 and the click buckle 21 can be easily slidably assembled.

[0074] like Figure 8 As shown, preferably, the four corners of the diamond block are rounded to avoid stress concentration during production, and the protrusion is an arc-shaped protrusion 213, which facilitates the limit block 123 to be snapped into the click buckle 21, making the operation smoother.

[0075] Since the click buckle 21 and the limit block 123 are in interference fit, the arc surface at the opening 212 can ensure that the cantilever at both sides of the click buckle will not undergo sudden changes during deformation, making the deformation process smoother.

[0076] Preferably, the lengths of the two diagonals of the diamond block are not equal, and the longer diagonal in the diamond block is on the same straight line as the moving trajectory of the switch control rod 30, wherein the angle close to the first via hole 121 is smaller than the angle away from the first via hole 121, and the diameter of the opening 212 is less than or equal to the length of the shorter diagonal in the diamond block.

[0077] In a specific embodiment, when the electrical stimulator body 10 is placed vertically, the diamond block is also arranged vertically, and the longer diagonal line of the diamond block is on the same straight line as the moving trajectory of the switch control rod 30, that is, the longer diagonal line of the diamond block is arranged vertically, and the shorter diagonal line is arranged horizontally.

[0078] Specifically, the angle below the shorter diagonal is defined as angle A, and the angle above the shorter diagonal is defined as angle B. The angle close to the first via hole 121 is smaller than the angle far from the first via hole 121 , that is, angle A is smaller than angle B.

[0079] An upward thrust is applied to the sliding switch key 20, and the click buckle 21 moves toward the limit block 123. When the limit block 123 slides into the click buckle 21, since the angle A of the limit block 123 is relatively small, the limit block 123 can more easily pass through the opening 212 of the click buckle 21 and enter the accommodating groove 211; a downward thrust is applied to the sliding switch key 20, and when the limit block 123 disengages from the click buckle 21, since the angle B of the limit block 123 is relatively large, it is obviously necessary to have a greater force than the upward thrust to push the sliding switch key 20 and disengage the limit block 123 from the click buckle 21, thereby improving the feel of use and preventing accidental touch from energizing the electrical stimulator body 10.

[0080] Embodiment 5

[0081] Please refer to Figure 7 On the basis of the first, second, third and fourth embodiments, the two inner sides of the sliding switch key 20 of the utility model are provided with undercuts 23, and the undercuts 23 face away from the sliding switch key 20;

[0082] The electrical stimulator body 10 is provided with a second through hole 122 that cooperates with the undercut 23 , and the undercut 23 slides in the second through hole 122 .

[0083] In this embodiment, the first via hole 121 is rectangular in shape, and the second via hole 122 is also rectangular in shape, which is convenient for processing and production.

[0084] Specifically, a second through hole 122 is provided on both sides of the first through hole 121 , and the central axis of the second through hole 122 is parallel to the central axis of the first through hole 121 . When the sliding switch key 20 drives the switch control rod 30 to slide in the first through hole 121 , the undercut 23 slides in the second through hole 122 .

[0085] In another embodiment, the first via hole 121 and the second via hole 122 may be disposed through each other.

[0086] Embodiment 5

[0087] Please refer to Figures 5 to 7 , based on the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment, the switch control rod 30 of the utility model is a square rod;

[0088] Baffles 24 are arranged opposite to each other on the inner side of the sliding switch key 20 in the extending direction of the moving track of the switch control rod 30 , and control rod locking grooves 22 are formed between the baffles 24 .

[0089] Specifically, since the switch control rod 30 is a square rod, the shape of the control rod positioning groove 22 also corresponds to a rectangular groove. The sliding switch key 20 moves only in one direction. By setting two baffles 24 at both ends of the moving direction, the switch control rod 30 can be blocked from moving on the sliding switch key 20 as the switch control rod 30 moves horizontally. The two baffles 24 set at intervals form the control rod positioning groove 22, and the structure is simple.

[0090] In order to enhance the limiting effect of the baffle, preferably, a support block 25 is further provided on the inner side of the sliding switch key 20 , and the support block 25 is attached to a side of the baffle 24 facing away from the control rod locking groove 22 .

[0091] The specific embodiments described above further describe the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific embodiment of the utility model and is not intended to limit the protection scope of the utility model. It is particularly pointed out that for those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
