In the related art, the self-cleaning dust collecting base fan is disposed in a fan chamber, the fan chamber is, for example, adjacent to and communicated with the dust collecting chamber, the dust collecting chamber is communicated with the fan chamber through a vent hole, and the fan in the fan chamber generates a suction force to suck air in the dust collecting chamber when working, so that the dust collecting chamber forms a negative pressure and is discharged to the outside of the pile through an air duct in the fan chamber. When the self-cleaning dust collecting seat performs dust collecting operation, the dust bag in the dust collecting bin is filled, so that the dust collecting air path is not smooth, and the negative pressure in the dust collecting bin is possibly too large to damage the fan.

Therefore, some embodiments of the present disclosure provide a self-cleaning dust collecting seat, wherein a safety valve is disposed in a dust collecting bin, so that when a negative pressure in the dust collecting bin is greater than a safety threshold, the dust collecting bin is communicated with the outside atmosphere, and the negative pressure in the dust collecting bin is prevented from being too large.

Fig. 8 is a schematic structural view of a dust collecting chamber provided in some embodiments of the present disclosure, which is combined with fig. 1-8, and some embodiments of the present disclosure provide a self-cleaning dust collecting receptacle, wherein the self-cleaning dust collecting receptacle comprises a self-cleaning dust collecting receptacle base plate 1000 and a self-cleaning dust collecting receptacle body 2000; the self-cleaning dust collecting base body 2000 is detachably connected to the self-cleaning dust collecting base bottom plate 1000. The self-cleaning dust collecting base body 2000 comprises a dust collecting chamber 3000, the dust collecting chamber 3000 is configured to form a negative pressure under the action of a blower, so that the garbage is collected in a garbage accommodating device, such as a dust bag, in the dust collecting chamber through a dust channel of the self-cleaning dust collecting base. A safety valve 2110 is arranged in the dust collecting bin 3000 and is configured to communicate the dust collecting bin 3000 with the outside atmosphere in response to the negative pressure in the dust collecting bin 3000 being greater than a safety threshold value, so as to avoid the excessive negative pressure in the dust collecting bin.

As shown in fig. 9 and 10, the relief valve 2110 includes a relief valve seat 2111 and a relief valve body 2112. A base through hole 21111 is formed in the safety valve base 2111; the safety valve body 2112 is buckled on the safety valve base 2111 to form a safety valve cavity 2113 with the safety valve base 2111, the dust collecting bin 3000 is communicated with the safety valve cavity 2113 through a base through hole 21111, a safety valve air inlet 21121 is arranged on one side of the safety valve body 2112 away from the safety valve base 2111, and the safety valve air inlet 21121 is communicated with the outside atmosphere. The relief valve 2110 further includes a relief valve core 2114 movably disposed within the relief valve cavity 2113 and configured to close off the relief valve inlet 21121 such that the relief valve cavity 2113 is isolated from the atmosphere.

Specifically, the safety valve core 2114 normally seals off the safety valve air inlet 21121, so that the safety valve cavity 2113 is isolated from the atmosphere, and the dust collecting bin 3000 forms a substantially closed space, thereby facilitating the dust collecting bin, and is configured such that the dust collecting bin 3000 forms a negative pressure under the action of the blower, so that the garbage is collected in a garbage accommodating device, such as a dust bag, in the dust collecting bin 3000 through the dust channel of the self-cleaning dust collecting seat.

When the self-cleaning dust collecting seat is in normal dust collecting operation, the negative pressure in the dust collecting bin is usually less than or equal to a safety threshold, at this time, the safety valve core blocks the air inlet of the safety valve, and the garbage is collected in a garbage accommodating device, such as a dust bag, in the dust collecting bin 3000 through the dust channel of the self-cleaning dust collecting seat. However, when the dust collecting device, such as a dust bag, is filled with dust or when the dust channel of the self-cleaning dust collecting base is blocked, the continuous operation of the fan may cause the negative pressure in the dust collecting bin 3000 to be too low, but the required dust collecting effect cannot be achieved. When the negative pressure in the dust collection bin 3000 is greater than the safety threshold, the external atmospheric pressure is higher than the pressures of the dust collection bin 3000 and the safety valve cavity 2113, under the action of the pressure difference between the two pressures, the safety valve core 2114 can move towards the safety valve base 2111, the safety valve air inlet 21121 is opened, so that the safety valve cavity is communicated with the outside through the safety valve air inlet 21121, the external atmosphere can enter the dust collection bin 3000 through the safety valve air inlet 21121, the safety valve cavity 2113 and the base through hole 21111 in sequence, and the excessively low negative pressure in the dust collection bin 3000 is balanced.

In some embodiments, as shown in fig. 9 and 10, the relief valve 2110 further includes a resilient member 2115, the resilient member 2115 being disposed within a relief valve cavity 2113 with a tendency to move the relief valve spool 2114 away from the relief valve seat 2111. The elastic member 2115 keeps the relief valve core 2114 in a state of closing off the relief valve intake port 21121.

In some embodiments, the resilient member 2115 is a spring that abuts the relief valve seat 2111 at one end and the relief valve spool 2114 at the other end.

In some embodiments, the relief valve seat 2111 includes a relief valve seat body 21112 and a protrusion 21113 extending from the relief valve seat body 21112 toward the relief valve inlet 21121, the seat through hole 21111 penetrates the relief valve seat body 21112 and the protrusion 21113, and includes a first sub-through hole 21111a and a second sub-through hole 21111b which are communicated with each other, the first sub-through hole 21111a and the second sub-through hole 21111b are sequentially disposed near the relief valve inlet 21121, the first sub-through hole 21111a communicates with the dust collecting bin 3000, and the second sub-through hole 21111b communicates with the relief valve cavity 2113. The inner diameter of the first sub-through hole 21111a is smaller than the inner diameter of the second sub-through hole 21111b, and one end of the spring is disposed in the second sub-through hole 21111b and abuts against the boundary between the first sub-through hole 21111a and the second sub-through hole 21111 b. The side of the safety valve core 2114 facing the safety valve seat 2111 is provided with a blind hole 21141, and the other end of the spring is disposed in the blind hole 21141, abutting against the bottom surface of the blind hole 21141. With this arrangement, since both ends of the spring are respectively accommodated in the second sub-through hole 21111b and the blind hole 21141, it is possible to keep the biasing force of the spring substantially in the horizontal direction in fig. 5, to avoid the elastic member from deviating from the horizontal direction during expansion and contraction, and to make the safety valve 2110 light and thin as a whole.

In some embodiments, as shown in fig. 9 and 10, the relief valve 2110 further includes a trigger switch 2116, the trigger switch 2116 being disposed within the relief valve cavity 2113 and configured to generate a control signal upon triggering, the control signal configured to sound an alarm and/or control the blower to stop operating.

In some embodiments, the relief valve spool 2114 contacts and activates the trigger switch 2116 in response to the relief valve spool 2114 moving toward the relief valve seat 2111 such that the distance between the relief valve spool 2114 and the relief valve seat 2111 decreases to a predetermined value.

The specific working principle of the safety valve in the present disclosure is as follows:

when the self-cleaning dust collecting base performs a dust collecting operation, the blower thereof generates a suction force to form a negative pressure in the dust collecting bin 3000, so that the garbage is collected in a garbage accommodating device, such as a dust bag, in the dust collecting bin 3000 through the dust channel of the self-cleaning dust collecting base. When the dust channel of the self-cleaning dust collecting base is blocked or a dust collecting device, such as a dust bag, in the dust collecting bin 3000 is filled with dust, the negative pressure in the dust collecting bin 3000 may exceed the safety threshold under the continuous operation of the fan. When the negative pressure in the dust collecting bin 3000 can be greater than the safety threshold, the safety valve core 2114 in the safety valve 2110 overcomes the elastic force of the elastic component 2115 and moves towards the safety valve base 2111 under the action of the pressure difference between the external atmospheric pressure and the negative pressure in the dust collecting bin 3000, so that the safety valve air inlet 21121 is opened, the dust collecting bin 3000 is communicated with the external atmosphere through the safety valve cavity 2113, and the excessive negative pressure in the dust collecting bin 3000 is avoided.

When the relief valve 2110 moves toward the relief valve seat 2111 by a distance exceeding a predetermined distance, i.e., the distance between the relief valve seat 2111 and the relief valve seat 2114 decreases to a predetermined value, the relief valve seat 2114 triggers a switch 2116. The trigger switch 2116 is, for example, a micro switch, and is configured to be triggered to send a control signal, and the control signal is, for example, configured to control the fan to stop working, so as to protect the fan. The control signal is configured, for example, to issue an alarm, such as a flashing alarm light, or to issue an alarm sound, prompting the user to check whether the dust bag is full or whether the dust channel of the self-cleaning dust receptacle is blocked.

In some embodiments, as shown in fig. 8, the safety valve 2110 is disposed on an inner sidewall of the dust bin 3000, such as a rear wall of the dust collection chamber 2100, and in other embodiments, the safety valve 2110 may be disposed at other locations, such as on a bottom wall of the dust bin.

A safety valve 2110 is arranged in the dust collecting bin 3000, and a trigger switch 2116 is arranged in the safety valve 2110. The safety valve 2110 is configured to trigger a trigger switch 2116 in a cavity in the safety valve in response to a negative pressure in the dust bin being greater than a safety threshold, a control signal being generated by the trigger switch 2116, the control signal being configured to issue an alarm and/or to control the fan to stop operating. Specifically, the control signal is configured to, for example, issue an alarm, such as an audio sound or a flashing light, or send a message to a terminal of a user, such as a mobile phone, to remind the user that the self-cleaning dust collecting receptacle is in an abnormal state, remind the user to check whether a dust bag is full, or whether a dust passage of the self-cleaning dust collecting receptacle is blocked. The control signal is also configured to control the fan to stop working, so that damage caused by overload operation of the fan is avoided.
