[0050] The embodiments of the present application provide an air tightness detection device, as shown in Figure 1 and Figure 2 The device comprises a base 100, a first mounting seat 200, a second mounting seat 300 and a pressing device 400 arranged on the base 100 in sequence, an air tightness detection assembly 500 and a toy water faucet 600, the air tightness detection assembly 500 is located on one side of the second mounting seat 300, the second mounting seat 300 is provided with an air passage 310, one end of the air passage 310 is in communication with the air tightness detection assembly 500. As shown in Figure 4 The toy water faucet 600 comprises a toy main body 610, a water inlet passage 620 arranged on one side of the toy main body 610, and a water outlet faucet 630 arranged on the other side of the toy main body 610, the water inlet passage 620 is provided with a water inlet, a water pump impeller is arranged in the water inlet passage 620, a valve is arranged between the water inlet passage 620 and the water outlet faucet 630, the switch 640 of the valve is arranged on the surface of the water outlet faucet 630, and the pressing device 400 is used for pressing or releasing the switch 640; the toy main body 610 is located between the first mounting seat 200 and the second mounting seat 300, the water inlet passage 620 is arranged on the first mounting seat 200, the water outlet faucet 630 is arranged on the second mounting seat 300, the water outlet faucet 630 is provided with a water outlet 650, and the water outlet 650 is in communication with the other end of the air passage 310. Under normal circumstances, the valve is in a closed state, so that even if the water inlet passage 620 is connected to a water source or an air source, water or gas cannot flow out of the water outlet 650 of the water outlet faucet 630. Only when the switch 640 is pressed, the valve is in an open state, at this time, the water inlet passage 620 is in communication with the water outlet faucet 630, when the water inlet contacts the water source, under the action of the water pump impeller, water will flow out of the water outlet 650 of the water outlet faucet 630; when the water inlet does not contact the water source and the valve is in an open state, the water pump impeller works, which will introduce air from the outside, and the air will pass through the water inlet passage 620 and the water outlet faucet 630 and be blown out of the water outlet 650.

[0051] According to the air tightness detection device, when the air tightness of the toy faucet 600 is to be detected, the toy main body 610 is arranged between the first mounting seat 200 and the second mounting seat 300, so that the water inlet channel 620 is arranged on the first mounting seat 200 and the water outlet faucet 630 is arranged on the second mounting seat 300, the first mounting seat 200 supports the water inlet channel 620, and the second mounting seat 300 supports the water outlet faucet 630, so that the support and fixation of the toy faucet 600 are realized. Meanwhile, the water outlet 650 of the water outlet faucet 630 is communicated with the air passage 310 of the second mounting seat 300, so that the air tightness detection of the toy faucet can be conveniently carried out subsequently. The power supply device supplies power to the toy faucet 600, so that the water pump impeller works, external air is introduced into the water inlet channel 620, at this time, the switch 640 is pressed by the pressing device 400, so that the valve is opened, the water inlet channel 620 and the water outlet faucet 630 are communicated, at this time, the air in the water inlet channel 620 enters the water outlet faucet 630, and is blown out from the water outlet 650 of the water outlet faucet 630, enters the air passage 310, and finally enters the air tightness detection assembly 500 from the air passage 310. If the air tightness detection assembly 500 can detect that the air flows out from the air passage 310, it is indicated that the air tightness of the toy faucet 600 is normal, and if the air tightness detection assembly 500 cannot detect that the air flows out from the air passage 310, it is indicated that the air tightness of the toy faucet 600 is abnormal.

[0052] According to the air tightness detection device, the air tightness of the toy faucet 600 can be detected, the structure is simple, the operation is convenient, and the detection efficiency is high.

[0053] As shown in Figure 1 and Figure 2 in some embodiments of the utility model, the first mounting seat 200 is provided with the first containing groove 210 matched with the water inlet channel 620, and the second mounting seat 300 is provided with the second containing groove 320 matched with the water outlet faucet 630. The first containing groove 210 is used for placing and fixing the water inlet channel 620, and the second containing groove 320 is used for placing and fixing the water outlet faucet 630, so that the water outlet 650 of the water outlet faucet 630 is communicated with the air passage 310.

[0054] As shown in Figure 1 and Figure 3As shown, in some embodiments of this utility model, the pressing device 400 includes a third mounting base 410, a fixed base 420, a handle 430, a connecting block 440, a telescopic rod 470, and a silicone head 460. The fixed base 420 is disposed on the third mounting base 410, one end of the fixed base 420 is rotatably connected to the handle 430, and the other end of the fixed base 420 is provided with a sleeve 450. The connecting block 440 is disposed on the fixed base 420, one end of the connecting block 440 is connected to the handle 430, and the other end of the connecting block 440 is connected to one end of the telescopic rod 470. The other end of the telescopic rod 470 is connected to the silicone head 460, and the telescopic rod 470 passes through the sleeve 450. When the handle 430 is pulled downwards (so that it is in the position of...), the pressing device 400... Figure 3 When the switch is in the above-sloping state, the connecting block 440 gradually changes from an upward-sloping posture to a horizontal posture, causing the telescopic rod 470 to move towards the second mounting base 300. The telescopic rod 470 causes the silicone head 460 to move until it contacts the switch 640, thereby pressing the switch 640 and opening the valve. When the handle 430 is pulled upward, the connecting block 440 is pulled by the handle 430, changing from a horizontal direction to an upward-sloping direction, causing the telescopic rod 470 to move away from the second mounting base 300, causing the silicone head 460 to release the switch 640, and the valve to close.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the airtightness detection component 500 includes a fourth mounting base 510, on which a pipe 520 is provided, and glass beads (not shown) are disposed inside the pipe 520. One end of the pipe 520 is connected to the ventilation channel 310. Specifically, if the airtightness of the toy faucet 600 is normal, after the water pump impeller rotates, external gas will enter the inlet channel 620 through the inlet, then enter the outlet faucet 630, and then flow out from the outlet 650 of the outlet faucet 630, and enter the ventilation channel 310 of the second mounting base 300, and finally enter the pipe 520 through the ventilation channel 310, thereby driving the glass beads inside the pipe 520 to move. If the toy faucet 600 is not airtight, after the water pump impeller rotates, outside air will enter the inlet channel 620 through the inlet, but cannot flow out through the outlet 630 and outlet 650. At this time, no air enters the pipe 520 through the vent channel 310, and therefore cannot move the glass beads inside the pipe 520. This airtightness detection component allows for a direct detection of whether the toy faucet 600 is airtight. It should be noted that the airtightness detection component 500 can also use a pressure sensor or other device to detect whether the air pressure flowing out of the vent channel 310 is normal.

[0056] Furthermore, such as Figure 4 and Figure 5As shown, in some embodiments of the utility model, the toy main body 610 is provided with a battery compartment 660, and the battery compartment 660 is used for placing the simulation battery 700, so that the power supply device supplies power to the toy faucet 600 through the simulation battery 700, and the water pump impeller can work.

[0057] Specifically, in order to make the toy faucet 600 work, it is usually necessary to install a real dry battery in its battery compartment 660 to make it work. However, if a real dry battery is used in the process of batch air tightness detection of the toy faucet 600, the consumption of dry batteries will be high, causing waste of energy and pollution of the environment. Therefore, the application proposes a simulation battery 700, which can simulate the power supply of a real dry battery to the toy faucet 600, thereby avoiding waste of dry batteries and environmental pollution. As Figures 5 to 7 As shown, in this example, the simulation battery 700 includes an insulating shell 710, a positive metal head 750, a negative metal sheet 760, a positive power line 791, and a negative power line 790, wherein the insulating shell 710 includes a first seat body 720, the first seat body 720 is internally provided with a first conductive circuit and a second conductive circuit, the first conductive circuit and the second conductive circuit are insulated from each other, the positive metal head 750 is arranged on one side of the first seat body 720, the negative metal sheet 760 is arranged on the other side of the first seat body 720, one end of the positive power line 791 is connected with the power supply device, the other end of the positive power line 791 is connected with one end of the first conductive circuit, the other end of the first conductive circuit is connected with the positive metal head 750, that is, the positive electrode of the power supply device is connected with the positive metal head 750 through the positive power line 791 and the first conductive circuit; one end of the negative power line 790 is connected with one end of the second conductive circuit, the other end of the second conductive circuit is connected with the negative metal sheet 760, the other end of the negative power line 790 is connected with the power supply device, that is, the negative electrode of the power supply device is connected with the negative metal sheet 760 through the negative power line 790 and the second conductive circuit. When the simulation battery 700 is installed in the battery compartment 660, the positive metal head 750 is in contact with the positive conductive sheet in the battery compartment 660, and the negative metal sheet 760 is in contact with the negative spring in the battery compartment 660. In this way, the power supply device, the negative power line 790, the second conductive circuit, the negative metal sheet 760, the toy faucet 600, the positive metal head 750, the first conductive circuit, the positive power line 791, and the power supply device form a complete power supply loop, and the power supply device can supply power to the toy faucet 600 through the simulation battery 700.

[0058] It should be noted that the simulation battery 700 described above is suitable for a toy faucet 600 that only needs one dry battery. For a toy faucet 600 that needs two dry batteries, such as Figures 5 to 7As shown, the insulating shell 710 further comprises a second seat body 730, the second seat body 730 is internally provided with a third conductive circuit, the second seat body 730 is arranged in parallel with the first seat body 710, one side of the second seat body 730 is provided with a mounting gap 731, the negative metal column 780 is arranged in the mounting gap 731, and the extension direction of the negative metal column 780 is vertically downward, the positive metal column 770 is arranged on the other side of the second seat body 730, the extension direction of the positive metal column 770 is parallel to the extension direction of the second seat body 730, and the positive metal column 770 and the negative metal column 780 are conductive through the third conductive circuit. Through such an arrangement, the simulation battery 700 can simulate two dry batteries, and the battery compartment 660 has two cavities for accommodating the first seat body 720 and the second seat body 730 respectively. The positive metal column 770 contacts the positive conductive sheet in the corresponding cavity of the battery compartment 660, and the negative metal column 780 contacts the negative spring in the corresponding cavity of the battery compartment 660. At the same time, the positive metal head 750 contacts the positive conductive sheet, and the negative metal column 780 contacts the negative spring, and the positive metal head 750 and the negative metal column 780 are connected through the conductive metal sheet, so that the positive metal head 750 and the negative metal column 780 are conductive. Through such an arrangement, the power supply device, the negative power line 790, the second conductive circuit, the negative metal sheet 760, the toy faucet 600, the positive metal column 770, the third conductive circuit, the negative metal column 780, the positive metal head 750, the first conductive circuit, the positive power line 791, and the power supply device form a complete power supply circuit, and the power supply device can supply power to the toy faucet 600 through the simulation battery 700. At the same time, by arranging the extension direction of the positive metal column 770 to be parallel to the extension direction of the second seat body 730 and the extension direction of the negative metal column 780 to be vertically downward, the effect of preventing the simulation battery 700 from being reversed can be achieved. If the simulation battery 700 is reversed, the positive metal column 770 will be arranged on the side of the negative spring, and the negative metal column 780 will be arranged on the side of the positive conductive sheet. Since the extension direction of the negative metal column 780 is vertically downward, the negative metal column 780 cannot contact the positive conductive sheet, so the circuit cannot be formed. Only when the simulation battery 700 is correctly placed in the battery compartment 660, the positive metal column 770 can contact the positive conductive sheet of the battery compartment 660 due to the outward extension of the positive metal column 770, and finally a circuit is formed.

[0059] In addition, as Figure 5 shown, a groove 740 is formed between the first seat body 720 and the second seat body 730, and a partition plate 661 is arranged in the battery compartment 660 and matched with the groove 740. The battery compartment 660 is divided into two cavities by the partition plate 661, and the two cavities are used to place the first seat body 720 and the second seat body 730 respectively. At the same time, the groove 740 is formed between the first seat body 720 and the second seat body 730 for avoiding the partition plate 661.

[0060] In some embodiments of the utility model, the power supply device is further connected with a voltmeter and an ammeter, and whether the working voltage and working current of the toy faucet 600 are normal is detected through the voltmeter and the ammeter.

[0061] Therefore, the air tightness detection device according to the embodiment of the application can conveniently detect the air tightness of the toy faucet 600, is simple and easy to operate, and has high detection efficiency.

[0062] The utility model is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the utility model.
