Detailed Description
In order to further describe the technical means and effects adopted by the present application to achieve the preset purpose, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the present application with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
As shown in fig. 1, the present invention discloses a sewage control device, comprising: a first cavity 11 with a water inlet 112, wherein a first water drain channel 111 is arranged at the cavity bottom of the first cavity 11; the first water valve is arranged in the first water drain channel 111, and comprises a first valve body 13 for sealing the first water drain channel 111, a first valve core 14 for driving the first valve body 13 to act, and a first elastic part (for example, the first elastic part is a spring) sleeved on the first valve core 14 to generate a downward restoring elastic force; a second cavity 12 communicated with the first drainage channel 111, wherein a second drainage channel 121 which is not coaxial with the first drainage channel 111 is arranged at the cavity bottom of the second cavity 12; the second water valve is arranged in the second water drain channel 121, has the same structure as the first water valve, and comprises a second valve body 17 for sealing the second water drain channel 121, a second valve core 18 for driving the second valve body 17 to act, and a second elastic part (for example, the second elastic part is a spring) arranged on the second valve core 18 to generate a downward restoring elastic force; the first valve core 14 for controlling the first water valve is a force transmission mechanism which is arranged below the first valve core 14 and is used for enabling the first water valve to be opened after the second water valve and to be closed before the second water valve.
The force transmission mechanism comprises a guide hole arranged at the bottom of the cavity of the second cavity 12 and a push rod 15 penetrating through the guide hole, a movable sealing connecting sleeve 16 (for example, the sealing connecting sleeve 16 is a sealing silica gel sleeve arranged at the guide hole and sleeved on the push rod 15), a preset distance is arranged between the upper end of the push rod 15 and the lower end of the first valve core 14, so that when a driving mechanism for driving the push rod 15 and the second valve core 18 of the second water valve acts on the push rod 15 and the second valve core 18 of the second water valve simultaneously, the push rod 15 moves upwards by no more than the preset distance, and is not abutted to the lower end of the first valve core 14, the second valve core 18 drives the second valve body 17 to move upwards to open the second water valve, and only when the push rod 15 moves upwards by more than the preset distance, the push rod 15 generates upward force on the first valve core 14 to drive the first valve body 13 to open the first water valve, thereby realizing that the first water valve is opened later than the second water valve; conversely, when the driving mechanism generates a force to the ejector rod 15 and the second valve core 18 of the second water valve to disappear, the ejector rod 15 and the second valve core 18 simultaneously start to descend so that after the first valve core 14 moves downwards to close the first water valve preferentially, the second valve core 18 continues to move downwards for a preset distance and then drives the second valve body 17 to close the second water valve.
Of course, an elastic element (for example, a spring) for generating a downward restoring elastic force to the ejector 15 is preferably disposed on the ejector 15, so that the ejector 15 moves downward by the restoring elastic force generated by the elastic element when no external force or small external force acts on the lower end of the ejector 15, thereby ensuring that the ejector 15 does not interfere with the first valve core 14 and does not affect the sealing of the first valve body 13 to the first drain channel 111.
The water outlet control device is arranged at the water outlet of the water tank to control the water outlet of the water tank, and is particularly suitable for electrical equipment such as a humidifier.
As shown in fig. 2 and 3, the present invention discloses a humidifier using the above-mentioned water supply control device, the humidifier comprising: a base 2; a water tank 3 arranged on the base 2, wherein a water outlet is arranged at the bottom of the water tank 3; an atomization cavity 4 arranged below the water tank 3, wherein an atomization element and a driving mechanism are arranged in the atomization cavity 4; the above-mentioned drain control means provided between the drain and the atomizing chamber 4, wherein the water inlet 112 of the first chamber 11 communicates with the drain of the water tank 3, and the second drain passage 121 communicates with the atomizing chamber 4. In addition, the water tank 3 has a top cover 31 with a mist outlet 311, and water can be added into the water tank 3 by opening the top cover 31; a mist guide tube 6 is provided between the mist outlet 311 and the mist chamber 4, and the mist guide tube 6 is preferably provided directly above the mist generating element.
In one embodiment, a filter assembly 19, which is a filter element or a filter screen, is arranged at the water inlet 112 of the first cavity 11 for blocking hair and large-particle impurities in the water tank 3 from entering the first cavity 11. For example, the inner side wall of the first cavity 11 is provided with threads, and the filter assembly 19 is screwed with the inner side wall of the first cavity 11 so as to facilitate disassembly and assembly without affecting use.
The driving mechanism is a lever type floating ball structure, an electromagnetic valve, a motor or an air pump and the like. Among them, the lever type floating ball structure is widely used in most of the current humidifiers due to its low cost and high reliability. The lever type floating ball structure comprises a supporting seat 51 arranged at the bottom of the atomizing cavity 4, a lever 52 arranged on the supporting seat 51, a floating ball 53 arranged at one end of the lever 51, and a first thrust part 54 and a second thrust part 55 which are respectively arranged at the other end of the lever and used for respectively generating upward acting force on the ejector rod 15 and the second valve core 18 when the atomizing cavity 4 lacks water.
In one embodiment, in addition to the control of the first water valve by setting a preset distance between the upper end of the jack 15 and the lower end of the first spool 14, the control of the first water valve may be achieved as follows: the vertical distance between the lower end of the ejector rod 15 and the first thrust portion 54 is set to be larger than the vertical distance between the lower end of the second valve core 18 and the second thrust portion 55 by the preset distance, so that when the lever 51 drives the first thrust portion 54 and the second thrust portion 55 to tilt up, the second thrust portion 55 pushes the second valve core 18 to move up to open the second water valve, and after the first valve core 54 needs to tilt up by the preset distance again, the first valve core 14 is driven to move up to open the first water valve, and the first water valve is opened after the second water valve is opened.
When the atomizing element in the atomizing cavity 4 works, water mist generated by water vibration is discharged from the mist outlet 311 through the mist guide cylinder 6, so that the water in the atomizing cavity 4 is consumed; along with the water level in the atomizing cavity 4 is reduced to a preset low water level, water in the water tank 3 is used for supplementing water to the atomizing cavity 4 through the water drainage control device. The specific process of supplementing water to the atomizing cavity 4 through the water drainage control device is as follows:
1. when the water level in the atomizing cavity 4 drops to a preset low water level, the floating ball 53 drops to a preset position, so that the lever 52 enables the first thrust part 54 and the second thrust part 55 to tilt upwards and respectively generate upward acting force on the ejector rod 15 and the second valve core 18, and the second valve core 18 drives the second valve body 17 to move upwards so as to open the second water valve to communicate the second cavity 12 with the atomizing cavity 4; because the preset distance is provided between the ejector rod 15 and the first valve body 14, when the second water valve is opened, the ejector rod 15 needs to move upwards for a sufficient distance before contacting the lower end of the first valve core 14, and under the pushing of the ejector rod 15, the first valve core 14 drives the first valve body 13 to move upwards, so that the first valve body 13 does not seal the first drainage channel 111 any more to open the first water valve, and water in the water tank 3 enters the first cavity 11 from the drainage port of the water tank 3, flows into the second cavity 12 through the first water valve and the first drainage channel 111, and flows into the atomization cavity 4 from the second water valve through the second drainage channel 121.
2. As the water level in the atomizing chamber 4 rises to be close to the preset high water level, the floating ball 53 rises so as to enable the first thrust part 54 and the second thrust part 55 to tilt downwards through the lever 52, and the first valve core 14 and the second valve core 18 move downwards under the action of respective restoring elastic force, so that the first valve core 14 drives the first valve body 13 to firstly seal the first water drain channel 111 to close the first water valve, water in the water tank 3 cannot enter the second chamber 12 any more, and water in the second chamber 12 can still flow into the atomizing chamber 4 through the second water drain channel 121; when the first water valve is closed, along with the water in the second cavity 12 continuously flows to the atomizing cavity 4 to enable the water level in the atomizing cavity 4 to continuously rise, the first thrust part 54 and the second thrust part 55 continuously tilt downwards, when the water level in the atomizing cavity 4 rises to a preset high water level after the water in the second cavity 12 flows to the atomizing cavity 4, at the moment, the second thrust part 55 does not apply force to the second valve core 18 or is smaller than the restoring elastic force of the second valve core 18, so that the second valve core 18 drives the second valve body 17 to move downwards to seal the second water drain channel 121, and the second water valve is closed.
Therefore, the invention has the preset distance between the upper end of the ejector rod 15 and the lower end of the first valve core 14, so that the first water valve and the second water valve are opened or closed in a delayed way, and the upper and lower positions or the coaxial arrangement between the first valve core 14 and the second valve core 18 do not cause the mutual correlation influence between the two, namely, when one water valve fails, the action of the other water valve is not influenced, the water draining sealing is ensured, the external factors of failure of the driving mechanism are removed, and the water draining control device is completely failed only when the first water valve and the second water valve fail at the same time, so that the invention has the double water draining protection effect through the first water valve and the second water valve, and the probability of the simultaneous failure of the first water valve and the second water valve is extremely low.
Furthermore, in addition to having the first and second water valves open or close with a delay, the provision of the first and second chambers 11, 12 also helps to reduce the probability of failure of the first and second water valves, because: in the water draining process, as the second water valve in the second cavity 12 is firstly opened and the first water valve in the first cavity 11 is not opened, after water in the water tank 3 flows to the first cavity 11 through the water draining port, impurities such as fine sand in the water can be pre-precipitated in the first cavity 11, and most of the impurities such as fine sand can be precipitated at the bottom of the first cavity 11 and positioned right below the water draining port of the water tank 3, so that the probability that the impurities such as fine sand in the water enter the first water draining channel 111 is reduced to reduce the failure probability of the first water valve; furthermore, even if the impurities such as fine sand enter the second cavity 12 through the first drainage channel 111, the first drainage channel 111 and the second drainage channel 121 are arranged in a staggered manner, so that the water entering the second cavity 12 gradually precipitates the impurities such as fine sand in the process of flowing to the second drainage channel 121, and the probability that the impurities such as fine sand in the water enter the second drainage channel 121 is reduced, so that the second water valve is in failure. Even, as shown in fig. 1, the water inlet of the first drainage channel 111 is provided at a position higher than the bottom of the first cavity 11, thereby blocking impurities such as fine sand precipitated in the bottom of the first cavity 11 from entering the first drainage channel 111; also, the water inlet of the second drain passage 121 is provided at a position higher than the bottom of the second chamber 12, thereby blocking the entry of impurities such as fine sand precipitated in the bottom of the first chamber 11 into the second drain passage 121.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
