Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a water purifier. Background Art

[0002] A water purifier, also called a water purifier, is mainly used for drinking water filtration. Physical filtration is usually used to effectively remove various pollutants in the water. The water purifier in the related art includes a filter, a liquid storage container, a liquid storage part, etc. The water filtered by the filter enters the liquid storage part for use by the user. The liquid storage container is connected to the liquid storage part. The liquid storage container can be, for example, a liquid level box, which is provided with a water level sensor, and the water level in the liquid storage container is used to reflect the water level in the liquid storage part. In addition, the connecting pipe on the liquid storage part is detachably connected to the connecting pipe on the liquid storage container by plugging and unplugging. However, when the user takes the liquid storage part, at the moment when the connecting pipe of the liquid storage part is separated from the connecting pipe of the liquid storage container, some water often leaks out of the connection port, resulting in a poor user experience. When the liquid storage container and the liquid storage part are raw water tanks or raw water tank seats, after the two are separated, there will also be water at the edge of the valve core of the raw water tank seat, or the raw water tank will drip.

[0050] In this arrangement, since one end of the sealing ring is sealed with the liquid storage container connecting tube, when the liquid storage component connecting seat is inserted into the liquid storage container connecting tube, the liquid storage component valve seat contacts the matching part to form a seal as soon as it contacts the matching part. At this time, there is a gap between the liquid storage container valve core and the liquid storage component valve core, and the two are not in contact, or the liquid storage container valve core and the liquid storage component valve core are in contact with each other and do not transmit force to each other. In this way, the liquid storage container valve assembly and the liquid storage component valve assembly are both in a closed state. As the liquid storage component connecting seat is inserted deeper, the matching part is pushed by the liquid storage component valve seat to move in the insertion direction relative to the liquid storage container valve core and undergoes elastic deformation, so that the liquid storage component valve seat and the matching part are pressed tightly and always maintain a sealed state. During this process, no matter whether the liquid storage container valve assembly and the liquid storage component valve assembly are opened or not, the water in the liquid storage container valve assembly and the liquid storage component valve assembly cannot leak out from the interface between the matching part and the liquid storage component valve seat. Therefore, no water leakage will occur during the entire insertion process of the liquid storage component connecting seat. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 This is a schematic cross-sectional view of the water purifier provided in an embodiment of the present application. Figure 3 for Figure 2 A local enlarged view of the A, Figure 4 This is a schematic diagram of the structure of the valve assembly of the liquid storage container in the water purifier provided in the embodiment of the present application. Figure 5 This is a schematic diagram of the structure of the liquid storage valve assembly in the water purifier provided in the embodiment of the present application. Figure 6 This is a structural schematic diagram of a water purifier provided in an embodiment of the present application in which a liquid storage container valve assembly and a liquid storage member valve assembly are both in an open state.

[0076] Reference Figure 1 , Figure 2 , Figure 3The water purifier 100 includes a liquid storage container 110 , a liquid storage member 120 , a liquid storage container valve assembly 130 and a liquid storage member valve assembly 140 .

[0077] The liquid storage container 110 is provided with a liquid storage container connecting tube 111 communicating with the inner cavity of the liquid storage container 110, and the liquid storage member 120 is provided with a liquid storage member connecting seat 121 communicating with the inner cavity of the liquid storage member 120. The insertion direction of the liquid storage member connecting seat 121 into the liquid storage container connecting tube 111 is defined as a first direction F. The liquid storage member connecting seat 121 may be, for example, a tubular member.

[0078] Combination Figure 3 , Figure 4 and Figure 5 The liquid storage container valve assembly 130 includes a sealing ring 150 and a liquid storage container valve core 132 that moves back and forth along the length direction of the liquid storage container connecting tube 111 to open and close the liquid storage container connecting tube 111. The liquid storage component valve assembly 140 includes a liquid storage component valve seat 141 and a liquid storage component valve core 142 arranged on the liquid storage component valve seat 141. The liquid storage component valve core 142 moves back and forth along the length direction of the liquid storage component connecting seat 121 to open and close the liquid storage component connecting seat 121.

[0079] One end of the sealing ring 150 is sealingly matched with the liquid storage container connecting pipe 111, and the other end is provided with a matching portion 151, and the matching portion 151 is movably sleeved on the outer periphery of the liquid storage container valve core 132.

[0080] The setting position of the liquid storage component valve seat 141 corresponds to the setting position of the matching part 151, and the setting position of the liquid storage component valve core 142 corresponds to the setting position of the liquid storage container valve core 132. The liquid storage component connecting seat 121 is located in the liquid storage container connecting tube 111, and the state in which the liquid storage component valve seat 141 just contacts the matching part 151 is defined as the initial state. In the initial state, there is a gap between the liquid storage container valve core 132 and the liquid storage component valve core 142, or the liquid storage container valve core 132 and the liquid storage component valve core 142 are in contact with each other and do not transmit force to each other.

[0081] The liquid storage container 110 is provided with a liquid storage container connecting tube 111 connected to the inner cavity of the liquid storage container 110, and the liquid storage component 120 is provided with a liquid storage component connecting seat 121 connected to the inner cavity of the liquid storage component 120. When the liquid storage component connecting seat 121 is inserted into the liquid storage container connecting tube 111 and the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are opened, the communication between the liquid storage container 110 and the liquid storage component 120 can be achieved.

[0082] Furthermore, one end of the sealing ring 150 is sealed and matched with the liquid storage container connecting pipe 111, and the other end is provided with a matching portion 151, which is movably sleeved on the outer periphery of the liquid storage container valve core 132, and the matching portion 151 can move relative to the liquid storage container valve core 132 in the first direction F or in the second direction S. The setting position of the liquid storage valve seat 141 corresponds to the setting position of the matching portion 151, and when the liquid storage connection seat 121 is inserted into the liquid storage container connecting pipe 111, when the liquid storage valve seat 141 just contacts the matching portion 151, there is a gap between the liquid storage container valve core 132 and the liquid storage valve core 142, or the liquid storage container valve core 132 and the liquid storage valve core 142 contact each other and do not transmit force to each other.

[0083] In this arrangement, since one end of the sealing ring 150 is sealed with the liquid storage container connecting tube 111, when the liquid storage component connecting seat 121 is inserted into the liquid storage container connecting tube 111, the liquid storage component valve seat 141 just contacts the matching portion 151 and forms a seal with the matching portion 151. At this time, there is a gap between the liquid storage container valve core 132 and the liquid storage component valve core 142, and the two are not in contact, or the liquid storage container valve core 132 and the liquid storage component valve core 142 are in contact with each other and do not transmit force to each other. In this way, the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are both in a closed state. With the liquid storage component connecting seat 121 inserted into the liquid storage container connecting tube 111, the liquid storage component valve seat 141 just contacts the matching portion 151 and forms a seal. 1 is inserted deeper, the matching portion 151 is pushed by the liquid storage component valve seat 141 to move in the insertion direction relative to the liquid storage container valve core 132 and undergoes elastic deformation, so that the liquid storage component valve seat 141 and the matching portion 151 are tightly pressed and always maintain a sealed state. During this process, no matter whether the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are opened or not, the water in the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 cannot leak out from the junction between the matching portion 151 and the liquid storage component valve seat 141. Therefore, during the entire insertion process of the liquid storage component connecting base 121, no water leakage will occur.

[0084] When the liquid storage component connection seat 121 is separated from the liquid storage container connection tube 111, contrary to the above process, as the liquid storage component connection seat 121 is pulled out, the liquid storage component valve core 142 and the liquid storage container valve core 132 will first break contact, so that the liquid storage component valve assembly 140 and the liquid storage container valve assembly 130 are closed respectively. Of course, as the liquid storage component valve seat 141 continues to move along the second direction S, the pressure on the matching portion 151 gradually decreases. Before the liquid storage component valve seat 141 leaves the matching portion 151, the liquid storage component valve seat 141 is in the elastic reset process, so it is always pressed against the matching portion 151 to maintain the sealing matching relationship between the two. In this process, no matter the liquid storage container valve assembly Regardless of the closing sequence of the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140, during the entire closing process of the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140, the water in the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 cannot leak out from the junction between the matching portion 151 and the liquid storage component valve seat 141. In other words, after the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are closed, the liquid storage component valve seat 141 and the liquid storage container valve seat 131 will be separated from contact and the sealing state will be released. This is compared with the situation in the related art that water always flows out during the closing process of the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140, which greatly improves the water leakage during the pulling out process. In addition, there is no possibility that dust and other debris will enter the liquid storage container 110.

[0085] In the present application, continue to refer to Figure 3 The liquid storage container valve assembly 130 also includes a liquid storage container valve seat 131, a liquid storage container valve core 132 is inserted into the liquid storage container valve seat 131, and the liquid storage container valve seat 131 is connected to the liquid storage container connecting pipe 111. The liquid storage container valve core 132 can move along a first direction F relative to the liquid storage container valve seat 131, or elastically reset along a second direction S opposite to the first direction F to open or close the valve hole 1311 of the liquid storage container valve seat; the first direction F is the direction in which the liquid storage component connecting seat 121 is inserted into the liquid storage container connecting pipe 111, and is parallel to the length direction of the liquid storage container connecting pipe 111.

[0086] Furthermore, the reservoir valve core 142 can move relative to the reservoir valve seat 141 in the second direction S, or elastically return to the first direction F, so as to open or close the valve hole 1411 of the reservoir valve seat.

[0087] The liquid storage container valve seat 131 is connected to the liquid storage container connecting pipe 111, and the liquid storage container valve core 132 can move along the first direction F relative to the liquid storage container valve seat 131 to open the valve hole 1311 of the liquid storage container valve seat. In addition, the liquid storage valve seat 141 is connected to the liquid storage connecting seat 121, and the liquid storage valve core 142 can move in the second direction S relative to the liquid storage valve seat 141 to open the valve hole 1411 of the liquid storage valve seat. The setting position of the liquid storage valve core 142 corresponds to the setting position of the liquid storage container valve core 132. In this way, when the liquid storage connecting seat 121 is inserted into the liquid storage container connecting tube 111, the liquid storage container valve assembly 130 and the liquid storage container valve assembly 140 interact with each other, and the liquid storage valve core 142 and the liquid storage container valve core 132 can be moved in the second direction S and the first direction F respectively to open the valve hole 1411 of the liquid storage valve seat and the valve hole 1311 of the liquid storage container valve seat, so that the liquid storage valve assembly 140 and the liquid storage container valve assembly 130 are both in an open state.

[0088] The liquid storage container valve core 132 can be elastically reset along the second direction S relative to the liquid storage container valve seat 131 to close the valve hole 1311 of the liquid storage container valve seat, and the liquid storage component valve core 142 can be elastically reset in the first direction F relative to the liquid storage component valve seat 141 to close the valve hole 1411 of the liquid storage component valve seat. In this way, when the liquid storage component connecting seat 121 is detached from the liquid storage container connecting tube 111, the liquid storage component valve core 142 and the liquid storage container valve core 132 are both elastically reset to close the valve hole 1411 of the liquid storage component valve seat and the valve hole 1311 of the liquid storage container valve seat, so that the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are both in a closed state.

[0089] In the embodiment of the present application, the matching portion is clearance-matched with the valve core 132 of the liquid storage container.

[0090] In the present application, continue to refer to Figure 4The liquid storage container valve core 132 includes a liquid storage container valve core body 1321 and a plurality of liquid storage container ribs 1322. The plurality of liquid storage container ribs 1322 are arranged at intervals and around the outer peripheral surface of the liquid storage container valve core body 1321. The matching portion 151 is constructed as an annular member and is sleeved on the outer peripheral side of each liquid storage container rib 1322 and is matched with the outer peripheral side of each liquid storage container rib 1322. The inner diameter of the matching portion 151 is less than 7 mm. In this way, a sealed water film can be formed between the inner wall of the matching portion 151 and the liquid storage container valve core 132 (forming a cross section). In this arrangement, since the outer end of the sealing ring 150 is sealed with the inner wall of the liquid storage container connecting tube 111, a sealed water film is formed between the matching portion 151 at the inner end of the sealing ring 150 and the valve core 132 of the liquid storage container. In this way, no matter during the insertion or removal of the liquid storage component connecting seat 121, after the liquid storage component valve seat 141 and the matching portion 151 are out of contact, the matching portion 151 will form a seal with the valve core 132 of the liquid storage container to prevent water in the liquid storage container valve assembly 130 from leaking out. In this way, water leakage will never occur during the entire removal process of the liquid storage component connecting seat 121.

[0091] Furthermore, the liquid storage container connecting pipe 111 , the liquid storage container valve core 132 and the sealing ring 80 together form an accommodating space C.

[0092] When the liquid storage member connection seat 121 is not inserted into the liquid storage container connection tube 111, water leaking from one side of the liquid storage container 110 can be temporarily stored in the accommodating space C, effectively preventing water from leaking from the liquid storage container connection tube 111. In addition, when the liquid storage container 110 and the liquid storage member 120 are a raw water tank or a raw water tank seat, after the two are separated, water leaking from one side of the liquid storage container 110 will also be temporarily stored in the accommodating space C and will not leak to the outside of the liquid storage container 110, which can prevent water dripping. In addition, there is no possibility that dust and other debris will enter the liquid storage container 110.

[0093] The sealing ring 80 is configured as an elastic member, and the matching portion 81 can move along the first direction or elastically reset along the second direction under the drive of the liquid storage valve seat 141 to reduce or increase the volume of the accommodating space C.

[0094] With such a configuration, when the liquid storage component connection seat 121 is inserted into the liquid storage container connection tube 111, the stale water in the accommodating space C can be squeezed out to prevent bacteria from growing there when the liquid storage component connection seat 121 is inserted into the liquid storage container connection tube 111. When the liquid storage component connection seat 121 is inserted into the liquid storage container connection tube 111 and is plugged in place, the liquid storage component valve seat 141 pushes the matching portion 151 to the position closest to the liquid storage container 110, and the volume of the accommodating space C is the smallest at this time.

[0095] In the present application, continue to refer to Figure 3 and Figure 4The sealing ring 150 includes an annular main body 152 and a constricted neck 153. The constricted neck 153 and the matching portion 151 surround the outside of the valve core 132 of the liquid storage container. One end of the constricted neck 153 is connected to the main body 152, and the other end is connected to the matching portion 151. The constricted neck 153 is configured as an elastic member. In this way, when the matching portion 151 is subjected to an external force, since the constricted neck 153 is an elastic member, the matching portion 151 can move in the first direction F or elastically reset in the second direction S relative to the valve core 132 of the liquid storage container. In specific implementation, the sealing ring 150 can be made of a material with elastic rebound ability such as rubber or silicone.

[0096] When implementing it specifically, you can Figure 3 As shown, the neck portion 153 and the matching portion 151 are both located inside the main body 152. Alternatively, the main body 152, the neck portion 153 and the matching portion 151 may be arranged in sequence along the second direction S.

[0097] Furthermore, the end of the main body 152 away from the neck 153 is provided with a sealing ring flange 1521 folded outward, the outer peripheral surface of the main body 152 is pressed against the inner wall of the liquid storage container connecting pipe 111, and the sealing ring flange 1521 is sleeved on the end of the liquid storage container connecting pipe 111 away from the liquid storage container 110. In this way, a good seal is formed between the sealing ring flange 1521 and the inner wall of the liquid storage container connecting pipe 111, and the sealing ring 150 can also be installed on the liquid storage container connecting pipe 111 through the installation space formed between the sealing ring flange 1521 and the main body 152.

[0098] In addition, the water purifier 100 further includes a cylindrical mounting cover 160, the end of which is provided with an inwardly folded mounting cover flange portion 161, and the mounting cover flange portion 161 presses the sealing ring flange portion 1521 against the end of the liquid storage container connecting pipe 111 away from the liquid storage container 110. In this way, the sealing ring 150 can be reliably fixed on the liquid storage container connecting pipe 111.

[0099] In the embodiment of the present application, the inner diameter of the matching portion 151 is smaller than or equal to the inner diameter of the reservoir valve seat 141, and the projections of the matching portion 151 and the reservoir valve seat 141 facing each other on a plane perpendicular to the first direction F have an overlapping portion. This arrangement facilitates the reservoir valve seat 141 to smoothly press the matching portion 151 and move in the first direction F.

[0100] Furthermore, the outer diameter of the liquid storage component connection seat 121 is smaller than the inner diameter of the main body 152. An annular protrusion 1522 is provided inside the main body 152. When the liquid storage component connection seat 121 is inserted into the liquid storage container connection tube 111, the protrusion 1522 presses against the outer wall of the liquid storage component connection seat 121. Such a configuration can also facilitate the smooth insertion of the liquid storage component connection seat 121 into the liquid storage container connection tube 111. The protrusion 1522 presses against the outer wall of the liquid storage component connection seat 121, which, on the one hand, makes the insertion operation more handy, and on the other hand, facilitates the liquid storage component connection seat 121 to form a seal with the sealing ring 150, thereby preventing the liquid storage component connection seat 121 from withdrawing from the liquid storage container connection tube 111.

[0101] Further, continue to refer to Figure 3 , Figure 5 and Figure 6 The surfaces opposite to the matching portion 151 and the liquid storage valve seat 141 are respectively defined as a first surface 1511 and a second surface 1512. In the initial state, the end of the liquid storage container valve core 132 that faces away from the inner cavity of the liquid storage container 110 protrudes from the first surface 1511.

[0102] The distance D1 between the end surface of the liquid storage container valve core 132 facing the liquid storage member valve core 142 and the first surface 1511 and the distance D2 between the end surface of the liquid storage member valve core 142 facing the liquid storage container valve core 132 and the second surface 1512 satisfy: D1<D2. Such a configuration facilitates that when the first surface 1511 and the second surface 1512 are in contact, there is still a gap between the liquid storage container valve core 132 and the liquid storage member valve core 142, ensuring that when the liquid storage member connecting seat 121 is inserted, the matching portion 151 and the liquid storage member valve seat 141 are first contacted to form a seal and then the liquid storage container valve assembly 130 and the liquid storage member valve assembly 140 are opened. At the same time, when the liquid storage member connecting seat 121 is pulled out, after the liquid storage container valve assembly 130 and the liquid storage member valve assembly 140 are closed, the matching portion 151 and the liquid storage member valve seat 141 are separated from contact.

[0103] Furthermore, the end surface of the mating portion 151 that is away from the first surface 1511 is defined as a third surface 1513, and a locally raised liquid storage container step portion 1323 is provided between the two ends of the liquid storage container valve core 132, and the liquid storage container step portion 1323 is blocked on the moving path of the mating portion 151 toward the first direction F.

[0104] The liquid storage container step portion 1323 includes a first step surface 1324 extending radially along the liquid storage container valve core 132, and the first step surface 1324 is arranged opposite to the third surface 1513. The distance D3 between the end face of the liquid storage container valve core 132 facing the liquid storage valve core 142 and the first step surface 1324 and the thickness dimension D4 of the matching portion 151 along the first direction F satisfies: D3>D4.

[0105] With such arrangement, during the insertion of the liquid storage component connecting seat 121, after the liquid storage component valve seat 141 contacts the sealing ring 150, as the sealing ring 150 is pressed and deformed, the liquid storage component valve core 142 contacts the liquid storage container valve core 132, and the liquid storage component valve core 142 is opened. As the liquid storage component connecting seat 121 is further inserted, the liquid storage component valve seat 141 can press the matching portion 151 to move in the first direction F relative to the liquid storage container valve core 132, until the third surface 1513 contacts the first step surface 1324, and the liquid storage component valve seat 141 continues to move forward along the first direction F against the liquid storage container step portion 1323 through the matching portion 151, pushing the liquid storage container valve core 132 to move in the first direction F to open the valve hole 1311 of the liquid storage container valve seat.

[0106] In the present application, continue to refer to Figure 4 The liquid storage container valve seat 131 includes a liquid storage container valve seat body 133, which is configured with a first accommodating cavity with openings at both ends, and the opening toward the inner cavity of the liquid storage container 110 forms a valve hole 1311 of the liquid storage container valve seat.

[0107] The liquid storage container valve core 132 penetrates the first accommodating cavity and cooperates with the cavity wall of the first accommodating cavity in a guiding manner, and the liquid storage container blocking end 134 of the liquid storage container valve core 132 enters the inner cavity of the liquid storage container 110 through the valve hole 1311 of the liquid storage container valve seat. A first sealing member 135 may also be provided on the liquid storage container blocking end 134 of the liquid storage container valve core 132, which is used to form a sealing cooperation with the valve hole 1311 of the liquid storage container valve seat when contacting the valve hole 1311 of the liquid storage container valve seat.

[0108] Further, refer to Figure 4 and Figure 5 The liquid storage container valve assembly 130 further includes a liquid storage container elastic member 136, which is disposed between the inner wall of the liquid storage container valve seat 131 and the liquid storage container valve core 132, so as to always apply an elastic force toward the second direction S to the liquid storage container valve core 132. In this way, the elastic reset of the liquid storage container valve core 132 can be achieved.

[0109] Further, refer to Figure 6 The outer surface of the liquid storage container valve core 132 is provided with at least one second step portion 137, and the two ends of the liquid storage container elastic member 136 are respectively pressed between the inner wall of the liquid storage container valve seat 131 and the at least one second step portion 137. In this way, the liquid storage container elastic member 136 can be simply positioned by being sleeved on the liquid storage container valve core 132, and the two ends are respectively pressed between the inner wall of the liquid storage container valve seat 131 and the second step portion 137.

[0110] Continue to refer to Figure 5The liquid storage valve seat 141 includes a liquid storage valve seat body 143, and the liquid storage valve seat body 143 is configured with a second accommodating cavity with two ends opened, and the opening away from the inner cavity of the liquid storage 120 forms a valve hole 1411 of the liquid storage valve seat.

[0111] The liquid storage valve core 142 penetrates the second accommodating cavity and cooperates with the cavity wall of the second accommodating cavity to guide, and the liquid storage blocking end 144 of the liquid storage valve core 142 blocks the valve hole 1411 of the liquid storage valve seat when it moves along the first direction F. An annular protrusion 1441 is provided on the outer side of the liquid storage blocking end 144. When the liquid storage valve core 142 moves until the annular protrusion 1441 is located outside the hole wall of the valve hole 1411 of the liquid storage valve seat, as shown in FIG. Figure 6 As shown, the reservoir valve assembly 140 is open.

[0112] In a specific implementation, the liquid storage valve seat body 143 may include two bases 145 and a plurality of connecting ribs 146 connected between the two bases 145. A second accommodating cavity is defined between the base 145 and the plurality of connecting ribs 146.

[0113] Further, see Figure 5 and Figure 6 The liquid storage valve assembly 140 further includes a liquid storage elastic member 147, which is disposed between the inner wall of the liquid storage valve seat 141 and the liquid storage blocking end 144 of the liquid storage valve core 142, so as to always apply an elastic force toward the first direction F to the liquid storage valve core 142. The elastic coefficient of the liquid storage elastic member 147 is smaller than the elastic coefficient of the liquid storage container elastic member 136. The arrangement of the liquid storage elastic member 147 can realize the elastic reset of the liquid storage valve core 142.

[0114] In addition, the elastic coefficient of the liquid storage elastic member 147 is smaller than the elastic coefficient of the liquid storage container elastic member 136, so that when the liquid storage valve core 142 and the liquid storage container valve core 132 are against each other during the insertion of the liquid storage connector 121, the displacement of the liquid storage valve core 142 is greater than the displacement of the liquid storage container valve core 132, so that the liquid storage valve assembly 140 opens before the liquid storage container valve assembly 130. During the removal of the liquid storage connector 121, the closing time of the liquid storage valve assembly 140 is later than that of the liquid storage container valve assembly 130, and thus the liquid storage valve assembly 140 is closed later.

[0115] Furthermore, the outer wall of the liquid storage member 120 is configured with a mounting cavity 122 that is connected to the inner cavity of the liquid storage member 120, and the liquid storage member connection seat 121 is installed in the mounting cavity 122. Outside the mounting cavity 122, an avoidance cavity 123 arranged around the mounting cavity 122 is also configured, and the avoidance cavity 123 can be inserted into the liquid storage container connection pipe 111.

[0116] In the embodiment of the present application, the liquid storage container 110 is connected to the atmosphere, and a water level sensor for detecting the water level is provided in the liquid storage container 110. In this way, when the liquid storage container 110 is connected to the liquid storage member 120, the water level in the liquid storage container 110 can reflect the water level in the liquid storage member 120.

[0117] Combine the following Figure 3 and Figure 6 The plugging and unplugging process of the liquid storage member 120 and the liquid storage container 110 in the water purifier 100 according to the embodiment of the present application is described.

[0118] Figure 3 The figure shows the initial state, when the liquid storage component connecting seat 121 is inserted into the liquid storage container connecting tube 111, the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are still in a closed state, and the second surface 1512 of the liquid storage component valve seat 141 just contacts the first surface 1511 of the matching portion 151. At this time, there is a gap between the liquid storage container valve core 132 and the liquid storage component valve core 142, and they are not in contact. The second surface 1512 of the liquid storage component valve seat 141 and the first surface 1511 of the matching portion 151 are in contact to form a seal, and the water in the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 cannot leak out.

[0119] When the liquid storage member connecting seat 121 is further inserted into the liquid storage container connecting tube 111 along the first direction F, the liquid storage container valve core 132 contacts the liquid storage member valve core 142. Since the elastic coefficient of the liquid storage container elastic member 136 is greater than the elastic coefficient of the liquid storage member elastic member 147, the liquid storage member valve core 142 is pushed open by the liquid storage container valve core 132, so that the liquid storage member valve assembly 140 is opened. In this process, since the second surface 1512 of the liquid storage member valve seat 141 and the first surface 1511 of the matching portion 151 are always in contact to form a seal, water will not leak from between the liquid storage member valve seat 141 and the matching portion 151.

[0120] Reference Figure 6 When the liquid storage component connection seat 121 is further inserted into the liquid storage container connection tube 111 along the first direction F, the liquid storage component valve seat 141 drives the matching portion 151 to move in the first direction F, causing the matching portion 151 to produce elastic deformation, while causing the matching portion 151 to press against the liquid storage container step portion 1323, and driving the liquid storage container valve core 132 to move in the first direction F, overcoming the elastic force of the liquid storage container elastic member 136, so that the liquid storage container valve core 132 is pushed open, and the liquid storage container valve assembly 130 is also opened. At this time, since the liquid storage container valve assembly 130 and the liquid storage component valve assembly 140 are both open, water can flow between the liquid storage component 120 and the communicating vessel. Figure 6In the embodiment, the second step portion 137 on the liquid storage container valve core 132 presses against the periphery of the valve hole 1311 of the liquid storage container valve seat, so that the liquid storage container valve seat 131 cannot continue to move in the first direction F. It should be noted that at this time, since there is water on both sides of the matching portion 151, even if a water film is formed between the matching portion 151 and the liquid storage container valve core 132, it will not affect the connectivity between the liquid storage container valve assembly 130 and the liquid storage valve assembly 140.

[0121] It can be understood that, since the second surface 1512 of the liquid storage valve seat 141 and the first surface 1511 of the matching portion 151 are always in contact to form a seal, water will not leak out from between the liquid storage valve seat 141 and the matching portion 151. In this process, the outer wall of the liquid storage connection seat 121 and the protrusion 1522 are always in interference fit, which can prevent the liquid storage connection seat 121 from withdrawing from the liquid storage container connection pipe 111 in the second direction S, and further prevent water from leaking out.

[0122] Contrary to the insertion process, when the liquid storage component 120 is pulled out, as the liquid storage component valve seat 141 withdraws along the second direction S, the liquid storage container elastic component 136 elastically resets, and the liquid storage container valve core 132 gradually moves in the second direction S, first closing the liquid storage container valve assembly 130. At this time, after the third surface 1513 of the matching portion 151 is separated from the second step portion 137, the liquid storage component valve seat 141 no longer applies a resisting force to the liquid storage container valve core 132 through the matching portion 151.

[0123] In addition, the liquid storage component connection seat 121 continues to withdraw. Since there is no pressure from the liquid storage component valve seat 141, the matching part 151 is also gradually elastically reset. During this process, the liquid storage component elastic part 147 is also gradually elastically reset to close the liquid storage component valve assembly 140. After the liquid storage component valve assembly 140 is completely closed, the liquid storage component connection seat 121 continues to withdraw. During this process, the surface of the liquid storage container 110 of the matching part 151 and the surface of the liquid storage component 120 of the liquid storage component valve seat 141 are always in contact and sealed, and no water leakage will occur. Of course, during this process, due to the formation of a water film between the inner wall of the matching part 151 and the liquid storage container valve core 132, during the reset process, the water on one side of the liquid storage container valve assembly 130 is stored in the space defined by the sealing ring 150 and the liquid storage container valve seat 131, and will not leak out. When the liquid storage component 120 continues to be pulled out, the matching part 151 and the liquid storage component valve seat 141 are out of contact.

[0124] Figure 7 This is a schematic diagram of another structure of a valve core of a liquid storage container in a water purifier provided in an embodiment of the present application. Figure 8 A schematic diagram of another structure of a liquid storage container valve assembly in a water purifier provided in an embodiment of the present application.

[0125] In the embodiment of the present application, based on the above embodiment, the structure of the liquid storage container valve assembly 130 is improved, and the remaining structures are similar to the above and will not be repeated here.

[0126] Reference Figure 7 and Figure 8 The liquid storage container connecting pipe 111, the liquid storage container valve core 132 and the sealing ring 150 together form an accommodating space C, which is connected to the liquid storage container 110, that is, the inner cavity of the communicating vessel 10 when the liquid storage container valve assembly 130 is opened. In this way, when the liquid storage component connecting seat 121 is not inserted into the liquid storage container connecting pipe 111, water can be temporarily stored in the accommodating space C without leaking out.

[0127] Furthermore, a plugging member 321 is provided on the liquid storage container valve core 132, and the plugging member 321 is used to block and cooperate with the matching portion 151 to seal the accommodating space C. In this way, when the liquid storage component connecting seat 121 is not inserted into the liquid storage container connecting tube 111, water can be better prevented from leaking from the sealed accommodating space C.

[0128] In the embodiment of the present application, the liquid storage container 110 is a liquid level box, and the liquid storage member 120 is a clean water tank; or

[0129] The liquid storage container 110 is a raw water tank seat, and the liquid storage member 120 is a raw water tank; or

[0130] The liquid storage container 110 is a raw water tank, and the liquid storage member 120 is a raw water tank seat.

[0131] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0132] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
