The first embodiment is as follows:
in the prior art, in order to detect the sealing performance of the motor box assembly of the swimming pool robot, the motor box assembly of the swimming pool robot is often placed into a sealed test box after being installed, the test box is inflated, and water is possibly injected into the test box, so that the motor box assembly of the swimming pool robot is at least partially immersed in water. Whether the air pressure in the test box is reduced or not is judged so as to judge whether the condition that air or water in the test box enters the motor box assembly of the swimming pool robot exists or not. However, in this method, because the volume of the swimming pool robot motor box assembly is relatively small compared with the test box, if the swimming pool robot motor box assembly leaks, the gas in the test box enters the swimming pool robot motor box assembly, the influence on the pressure change in the test box is small, the test effect is poor, the test is inconvenient, and the precision is poor.

fig. 7 is a schematic structural view of a motor box assembly of a swimming pool robot according to a fourth embodiment of the present invention; as shown in fig. 7, a test hole is formed at the bottom surface of case 120, and accordingly, one-way ratchet assembly 200 is also installed at the bottom surface where the test hole is formed.
Example five:
the embodiment five still provides a swimming pool robot, including casing, advancing mechanism, clean mechanism and foretell swimming pool robot motor box subassembly.
By providing the aforementioned swimming pool robot motor box assembly in the swimming pool robot, accordingly, the swimming pool robot has all the advantages of the aforementioned swimming pool robot motor box assembly, which is not described herein in detail.
Example six:
fig. 8 is a schematic structural view of a sealing detection apparatus for a motor box assembly of a swimming pool robot according to a fifth embodiment of the present invention. As shown in fig. 8, in the swimming pool robot motor box assembly detection apparatus according to the sixth embodiment of the present invention, in the swimming pool robot motor box assembly 100, the air pressure measuring apparatus 300, and the inflator 400 of any one of the above embodiments, the one-way check assembly 200 is connected to the air pressure measuring apparatus 300, and the air pressure measuring apparatus 300 is configured to be connected to the inflator 400. Wherein the air pump can be used as the air charging device 400.
Although the contents shown in fig. 8 are shown based on the swimming pool robot motor box assembly 100 provided in the first embodiment, it should be clear to those skilled in the art that the sealing detection device for the swimming pool robot motor box assembly can also be formed based on the swimming pool robot motor box assembly 100 provided in the second to fourth embodiments, and the description thereof is omitted.
As shown in fig. 8, preferably, the air pressure measuring device 300 is a barometer. Wherein, the two ends of the barometer are respectively connected with the inflation device 400 and the test hole 111. Of course, in another implementation, an electronic pressure sensor may be used, and the electronic pressure sensor may upload the value to the controller, and the controller controls the electronic display device to display the pressure value.
In this embodiment, a barometer is used as the barometer device 300, which can directly read the barometric pressure value from the barometer for the operator to observe. Meanwhile, the cost of the detection device is reduced.
Example six:
the sixth embodiment of the invention also provides a method for sealing and detecting the motor box assembly of the swimming pool robot, which applies any one of the above sealing and detecting devices of the motor box assembly of the swimming pool robot, connects the air pressure measuring device 300 with the testing hole 111, inflates the accommodating cavity of the motor box assembly 100 of the swimming pool robot through the air pressure measuring device 300 and the testing hole 111, obtains the first pressure value of the air pressure measuring device 300, and observes the second pressure value of the air pressure measuring device 300 after the first preset time; if the second pressure value is the same as the first pressure value, the sealing performance of the motor box assembly 100 of the swimming pool robot is determined to be qualified, and/or if the second pressure value is smaller than the first pressure value, the sealing performance of the motor box assembly 100 of the swimming pool robot is determined to be unqualified.
Wherein the first pressure value is a pressure value which is greater than the air pressure of 10kPa-20kPa during the test, and is specifically 15kPa. The first predetermined time period is a time period of the pressure maintaining period after the swimming pool robot motor box assembly 100 is inflated, and specifically, the first predetermined time period may be 6s to 15s, and is preferably 10s. The second pressure value is a pressure value displayed by observing the air pressure measuring device 300 after the first preset time period. In addition, before inflating the pool robot motor enclosure assembly 100, there may also be a balancing phase in which the air pressure in the pool robot motor enclosure assembly 100 tends to stabilize uniformly. For example, the period of the equilibration period may be from 2s to 4s, preferably 3s.
After directly aerifing to swimming pool robot motor box subassembly 100, the atmospheric pressure of observing swimming pool robot motor box subassembly 100 changes, can directly reflect whether air leakage takes place for swimming pool robot motor box subassembly 100 to confirm whether its sealing performance is passed, greatly improved the convenience and the precision that detect.
In addition, compared with the conventional method for testing box inflation, the method for testing sealing provided by the embodiment has the advantages that if the test is performed in a water-free environment, the structure of the inflation device 500 is simpler than that of the air suction device, so that the cost of the sealing test device can be reduced. If tested in a water environment, the inflation test can protect the systems inside the pool robot motor box assembly 100; even the result that detects is that sealing performance is not too close, and the swimming pool robot motor box subassembly 100 appears revealing, so the gaseous pressurize effect that plays that swimming pool robot motor box subassembly 100 fills into, and the atmospheric pressure in the swimming pool robot motor box subassembly 100 is also bigger than the outside, can not let outside water get into. And bleed and detect, the risk is obviously greater than aerifing the detection, and swimming pool robot motor box subassembly 100 is sealed not tight, leads to water to enter into swimming pool robot motor box subassembly 100 easily after the detection, produces the pollution to the device wherein. Moreover, if it is qualified to detect the proof sealing performance, swimming pool robot motor box subassembly 100 drops into follow-up use in-process, and the atmospheric pressure in swimming pool robot motor box subassembly 100 is also greater than the outside to still can play the pressurize effect, even along with the extension of live time, the sealing performance of swimming pool robot motor box subassembly 100 descends, and the higher swimming pool robot motor box subassembly 100 of its interior atmospheric pressure also is outwards bubbling, and not inwards leak water. Compared with water leakage, the bubble is a phenomenon which is easier to observe, and the detection mode is also beneficial to a user to find out problems in time later for maintenance.
