[0030] As Figure 1 、 Figure 2 、 Figure 3 As shown, a three-pin five-hole energy storage socket with a safety door provided by the present invention includes a base 10 and a panel 20 provided at the open end of the base 10. The panel 20 is provided with two jacks corresponding to a single-phase two-pole plug (referred to as a two-pin plug) and three jacks corresponding to a single-phase two-pole grounded plug (referred to as a three-pin plug). Among them, the ground wire jack in the three jacks is arranged side by side with the positive jack and the negative jack in the two jacks, and the ground wire jack is located in the middle of the positive jack and the negative jack.
[0031] Inside the base 10, there is a support plate 30 and a contact component assembly 40 corresponding to the three-pin socket and the two-pin socket. The upper end of the contact component assembly 40 is located below the support plate 30, and through holes corresponding to the contact component assembly 40 are provided on the support plate 30. On the bottom plate of the support plate 30, a first safety door 50 and a second safety door 60 are slidably provided. Among them, the first safety door 50 and the second safety door 60 are arranged side by side. The first safety door 50 is located above the positive contact and the negative contact in the two-pin socket, and the second safety door 60 is located above the positive contact and the negative contact in the three-pin socket. Ramps are respectively provided on the first safety door 50 and the second safety door 60, and they can be moved to open the through holes corresponding to the positive contact and the negative contact under the pressure of the plug. On the opposite side edges of the first safety door 50 and the second safety door 60, a first support plate and a second support plate are respectively provided. A return spring 70 is provided between the first support plate and the second support plate, which is used to reset the corresponding first safety door 50 or second safety door 60 when the plug is pulled out, so as to block the through holes corresponding to the positive contact and the negative contact.
[0032] As Figure 4 shown, the support plate 30 includes a bottom plate 31, on which through holes corresponding to the contact component assembly 40 are provided. On the top surface of the bottom plate 31, a first guide plate 32, a second guide plate 33, a third guide plate 34 and a fourth guide plate 35 are provided. The first guide plate 32 and the second guide plate 33 respectively extend upward along the side walls of the through holes corresponding to the two-pin socket, and the third guide plate 34 and the fourth guide plate 35 respectively extend upward along the side walls of the through holes corresponding to the positive pin socket and the negative pin socket in the three-pin socket. On two opposite side edges of the bottom plate 31, a first baffle 36 and a second baffle 37 are respectively provided.
[0033] As Figure 5 shown, the first safety door 50 has a rectangular first frame 51. A first limit block 52 is provided on one side surface of the first frame 51, and a first support plate 53 is provided on the other side surface. A first guide shaft 54 is provided on the first support plate 53. The inner cavity of the first frame 51 is divided into a first chamber and a second chamber by a first partition plate 55. The first chamber corresponds to the positive pin socket in the two-pin socket, and the second chamber corresponds to the negative pin socket in the two-pin socket. The first partition plate 55 is perpendicular to the side edge of the first frame 51. The first guide plate 32 and the second guide plate 33 are respectively inserted into the first chamber and the second chamber. On the side surface of the first partition plate 55 facing the first chamber, a first ramp 56 is provided, and the bottom edge of the first ramp 56 abuts against the first guide plate 32.
[0034] As Figure 6As shown in the figure, the second safety door 60 has a rectangular second frame 61. A second limiting block 62 is provided on one side of the second frame 61, and a second support plate 63 is provided on the other side. A second guiding shaft 64 is provided on the second support plate 63. The inner cavity of the second frame 61 is separated into a third cavity and a fourth cavity by a second partition plate 65. The third cavity corresponds to the positive jack in the three jacks, and the fourth cavity corresponds to the negative jack in the three jacks. The second partition plate 65 is inclined with respect to the side of the second frame 61, and the inclination angle is the same as the angle of the positive insertion piece or the negative insertion piece in the plug. The third guiding plate 34 and the fourth guiding plate 35 are respectively inserted into the third cavity and the fourth cavity. The side of the second partition plate 65 facing the third cavity is provided with a second slope 66, and the bottom edge of the second slope 66 abuts against the third guiding plate 34.
[0035] The first safety door 50 and the second safety door 60 are arranged side by side. Among them, the first limiting block 52 and the second limiting block 62 are respectively arranged opposite to the first baffle 36 and the second baffle 37, thereby restricting the moving distances of the first safety door 50 and the second safety door 60. The first support plate 53 and the second support plate 63 are arranged opposite to each other, and a return spring 70 is arranged between the first support plate 53 and the second support plate 63 to realize the reset of the first safety door 50 or the second safety door 60. In this embodiment, the two ends of the return spring 70 are respectively sleeved on the first guiding shaft 54 and the second guiding shaft 64, so that the return spring 70 will not fall off, improving the use reliability.
[0036] The working principle of the three-pin and five-hole energy storage socket with a safety door provided by this application is as follows:
[0037] When using a single-phase two-pole plug, the positive insertion piece presses down the first slope 56, causing the first safety door 50 to move towards the direction of the negative contact, opening the corresponding through hole on the support plate 30, and enabling the single-phase two-pole plug to be inserted into the corresponding contact. When the single-phase two-pole plug is pulled out, under the action of the return spring 70, the first safety door 50 moves towards the direction of the positive contact, closing the corresponding through hole on the support plate 30.
[0038] When using a single-phase two-pole plug with a ground wire, the negative insertion piece presses down the second slope 66, causing the second safety door 60 to move towards the direction of the positive contact, opening the corresponding through hole on the support plate 30, and enabling the single-phase two-pole plug with a ground wire to be inserted into the corresponding contact. When the single-phase two-pole plug with a ground wire is pulled out, under the action of the return spring 70, the second safety door 60 moves towards the direction of the negative contact, closing the corresponding through hole on the support plate 30.
[0039] Based on the description of the above specific embodiments, compared with the prior art, the three-pin and five-hole energy storage socket with a safety door provided by the present utility model has the following advantages:
[0040] First, the existing sparkling water machines are equipped with only one automatic pressure relief valve. When this automatic pressure relief valve fails, potential safety hazards may occur. In the solution of this application, the three-pin five-hole energy storage socket with a safety door includes a primary pressure relief valve and a secondary pressure relief valve. When the primary pressure relief valve fails, the secondary pressure relief valve can automatically relieve pressure, achieving a dual protection function and improving the safety of using the sparkling water machine.
[0041] Second, some existing sparkling water machines are equipped with an additional manual pressure relief valve on the basis of an automatic pressure relief valve. When the automatic pressure relief valve fails, pressure is relieved through the manual pressure relief valve, but it is not convenient to use. In the solution of this utility model, both the primary pressure relief valve and the secondary pressure relief valve in the dual protection automatic pressure relief device are automatically controlled, without manual operation, and are more convenient to use.
[0042] Third, in this application, two spool assemblies are arranged in one valve body of the primary pressure relief valve. When one spool assembly gets stuck, the other spool assembly can automatically open to relieve pressure, achieving a dual protection function and further improving the safety of using the sparkling water machine.
[0043] Fourth, a guide sleeve is sleeved on the spool of the spool assembly. The guide sleeve is adapted to the diameter of the valve cavity, making the movement of the spool assembly in the valve cavity smoother, with a fast response speed, and can prevent the spool from tilting and jamming during movement.
[0044] Fifth, the spool and the guide sleeve are detachably connected, which is convenient for disassembly and assembly, can be replaced separately, and reduces costs.
[0045] Finally, it should also be noted that the terms "including", "comprising" or any other variant thereof used in this article are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0046] The present utility model is not limited to the above-mentioned best implementation mode. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model.
