Description

Technical Field

[0001] The present invention relates to the field of cleaning tools, in particular to a clean water pollution-proof cleaning bucket and a mop bucket. Background Art

[0002] The mop bucket used for cleaning flat mops has, after continuous updates and upgrades, a function that generally includes a cleaning function and a dehydration function after cleaning.

[0003] The structure disclosed in the Chinese patent application number CN201710221885.1, entitled "Standable Squeezable Flat Mop Cleaning Tool," divides the mop bucket into independent washing and dehydration zones, with a stroking extrusion device disposed above the washing zone and above the dehydration zone, respectively. Water is poured into the washing zone, while no water is contained in the dehydration zone. After the flat mop is inserted into the stroking extrusion device above the washing zone and enters the washing zone, the wipes on the flat mop will come into contact with the water in the washing zone, thereby achieving cleaning of the flat mop during the process of moving the flat mop up and down. The flat mop is then inserted into the stroking extrusion device in the dehydration zone and enters the dehydration zone. During the process of moving the flat mop up and down, since there is no water in the dehydration zone, excess water remaining on the wipes on the flat mop will be squeezed out, thereby achieving the function of dehydrating the flat mop.

[0004] The above setting method requires the flat plate to be switched between the two openings to achieve the purpose of cleaning and dehydration, so it is very inconvenient to operate.

[0005] Based on the above problems, the structure disclosed in the Chinese patent with application number CN20212054955.0 and name is a water-squeezing mop bucket. The bucket body is divided into an independent clean water bucket and an independent sewage bucket. A cleaning bucket is arranged between the clean water bucket and the sewage bucket. The mouth of the cleaning bucket is provided with a stroking extrusion device for squeezing the flat mop head. The stroking extrusion device includes a socket for passing the flat mop head, and an extrusion piece arranged on one side of the socket for squeezing the wipe of the flat mop head. The side of the extrusion piece facing away from the cleaning bucket guides to the sewage bucket. The barrel body of the cleaning bucket is provided with a throttling hole connected to the clean water chamber.

[0006] With the above arrangement, the flat mop head is inserted into the cleaning bucket. As the flat mop head descends, the flat mop head is soaked with the clean water in the cleaning bucket. Then, as the flat mop head rises, the dirty water on the flat mop head is squeezed into the sewage bucket under the action of the stroking and squeezing device. The advantage of this arrangement is that it can ensure that there is always relatively clean water in the cleaning bucket, ensuring that the mop head can be completely cleaned.

[0007] However, when the cleaning bucket is used to clean the mop, although the sewage in the mop enters the sewage bucket through the rubbing and squeezing device, when the mop is soaked again, the water in the cleaning bucket will still be slightly contaminated, and the throttle hole runs through the cleaning bucket and the clean water bucket, which will still cause the water in the cleaning bucket to become turbid. Summary of the Invention

[0008] Aiming at the disadvantage that the clean water in the prior art cleaning bucket is easily contaminated by the water in the cleaning bucket, the first object of the present invention is to provide a clean water pollution-proof cleaning bucket that can significantly reduce the contamination of water cups in the cleaning bucket.

[0009] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0010] A clean water pollution-proof cleaning bucket comprises an independently arranged clean water bucket, a cleaning bucket, and a water guiding mechanism for guiding water in the clean water bucket into the cleaning bucket. The water guiding mechanism comprises a water storage chamber. On both sides of the water storage chamber, a water seepage hole connected to the clean water bucket and a water outlet hole connected to the cleaning bucket are respectively provided. The water outlet hole is higher than the water seepage hole. A sealing lifting member is provided in the water storage chamber. The sealing member can completely block the water outlet hole when descending and expose at least a part of the water outlet hole after rising. The lifting of the sealing member is controlled by the lifting movement of a flat mop head in the water storage chamber. The rate at which the sealing member rises to expose the water outlet hole is much lower than one lifting cycle of the flat mop head.

[0011] By adopting the above scheme, the water outlet hole is higher than the seepage hole. When the seal is squeezed down by the flat mop head to completely block the water outlet hole, the cleaning bucket is isolated from the water storage bucket. When the time for one lifting and lowering stroke of the flat mop head is less than the time for the seal to open the water outlet hole, the seal is always in a state of sealing the water outlet hole during the entire cleaning cycle, thereby preventing the water in the cleaning bucket from mixing into the water storage chamber, and finally preventing the water in the cleaning bucket from mixing into the clean water bucket, thereby ensuring the water quality in the clean water bucket.

[0012] Preferably, an elastic member is provided in the seal to drive the seal to an upward state, and a matching member is provided at the upper end of the seal to pass out of the water storage chamber and elastically abut against the flat mop head inserted into the cleaning bucket.

[0013] With the above solution, the matching piece seal extends out of the water storage chamber, making it easier to fit with the flat mop head. The maximum lifting stroke of the seal is the extended length of the matching piece.

[0014] Preferably, the sealing member and the fitting member are integrally provided and are in the shape of a barrel with the opening downward, and a pressure reducing mechanism for quickly draining the water in the water storage chamber is provided on the water storage chamber or the fitting member.

[0015] By adopting the above solution, the setting of the pressure reducing mechanism and the discharge of water in the water storage chamber can ensure that the seal can be lowered to a sufficient depth to ensure that the flat mop head can be lowered to be completely soaked. At the same time, it significantly increases the time required for the seal to rise and open the water outlet, further improving the performance of isolating the water storage chamber and the cleaning bucket.

[0016] Preferably, the pressure reducing mechanism includes a drainage hole provided on the upper end of the fitting or the water storage chamber and a sealing body which opens or closes the drainage hole as the pressure in the water storage chamber increases or decreases.

[0017] By adopting the above scheme, since the matching piece is connected to the water storage chamber, the part of the matching piece extending outside the water storage chamber and the drainage hole are provided on the water storage chamber, and the drainage hole is opened and closed by using the sealing body, both of which can realize the function of timely draining the water in the water storage chamber to reduce the pressure when the drainage hole is opened.

[0018] Preferably, a pressure reducing member connected to the bottom of the water storage chamber is provided on one side of the water storage chamber, the drainage hole is provided on the upper end of the pressure reducing member, and a sealing body capable of opening or closing the drainage hole is provided on the pressure reducing member.

[0019] With the above solution, the pressure reducing member is connected to the water storage chamber. Therefore, a drainage hole is provided on the pressure reducing member and opened and closed by the sealing body, thereby also realizing the function of draining the water in the water storage chamber.

[0020] Preferably, the pressure reducing member is arranged in the cleaning bucket or the clean water bucket.

[0021] With the above solution, the pressure reducing component is set in the cleaning bucket, and it only needs to not interfere with the lifting and lowering of the mop; if the pressure reducing component is set in the clean water bucket, the effect will be better, because the water in the water storage chamber enters the clean water bucket, which will not increase the amount of water in the cleaning bucket, which is conducive to shortening the mop drying time.

[0022] Preferably, an extension tube is extended from the upper end of the fitting or the upper end of the pressure reducing member to prevent external factors from interfering with the opening and closing of the drainage hole of the sealing body.

[0023] With the above solution, the provision of the extension tube can conceal the movement of the sealing member and prevent the sealing member from being affected by the flat mop head or other factors.

[0024] Preferably, the sealing body is an elastic plug, which includes a plug post that is plugged into the upper end of the mating piece, an elastic sealing sheet provided at the upper end of the plug post, and a limit block provided at the lower end of the plug post to limit its escape from the mating piece.

[0025] With the above solution, when the flat mop head squeezes the sealing body and descends, the water pressure in the water storage chamber hits the elastic sealing piece, and the outer edge of the elastic sealing piece folds upward to expose the drainage hole, and the water in the water storage chamber is discharged into the cleaning bucket through the drainage hole; when the flat mop head moves upward, the sealing piece moves upward under the action of the elastic piece, and the negative pressure in the water storage chamber drives the elastic sealing piece downward to press against the upper end surface of the mating piece, thereby blocking the drainage hole.

[0026] Preferably, the sealing body is a sealing ball located at the upper end of the fitting, the upper end of the fitting is configured to be in an arc shape that fits the sealing ball, and a limiting member is provided on the extension tube to limit the sealing ball from falling out.

[0027] When the above solution is adopted, when the seal descends, there is positive pressure in the water storage chamber, and the sealing ball rises to open the drainage hole; during the process of the seal rising and resetting, when there is negative pressure in the water storage chamber, the sealing ball descends to block the drainage hole, and the limiter limits the sealing ball from escaping the extension tube.

[0028] Preferably, the limiting member is a horizontally arranged limiting pin, and insertion holes for interference insertion of the limiting pin are provided on both side walls of the extension tube.

[0029] With the above solution, the limit pin is horizontally inserted into the upper end of the lifting ball. When the lifting ball rises to abut against the limit pin, the limit pin limits its upward movement.

[0030] Preferably, the limiting member is a sealing ring plug with an elastic sealing cover provided on the upper end of the extension tube and having an inner diameter larger than that of the sealing ball.

[0031] With the above solution, the sealing ring plug cover is arranged on the extension tube, which can not only limit the escape of the sealing ball, but also smoothly discharge the water in the water storage chamber.

[0032] Preferably, the upper end of the fitting is configured to be in an arc shape that fits the sealing ball.

[0033] With the above solution, the upper end of the fitting is arranged in an arc shape, which can increase the contact area with the sealing ball and improve the sealing performance of the drainage hole after the sealing ball descends.

[0034] Preferably, the sealing body is made of elastic material.

[0035] With the above solution, the sealing body is directly supported by the elastic material and has a certain deformation ability, which can increase the sealing performance of blocking the drainage hole.

[0036] Preferably, a mounting mechanism is provided on the water storage chamber to facilitate the installation of the sealing member and the elastic member.

[0037] With the above solution, the sealing member and the elastic member are accessories to be installed subsequently, and both can be installed in the water storage chamber through the installation mechanism.

[0038] Preferably, the installation mechanism includes a slot hole opened at the bottom of the water storage chamber for inserting the sealing member and the elastic member, and a sealing cover sealed on the slot hole.

[0039] With the above solution, after the seal and elastic member are inserted into the water storage chamber, the sealing cover is sealed and fixed to the bottom of the water storage chamber, sealing the slot hole while providing support force for the elastic member, driving the seal to rise to the maximum stroke.

[0040] Preferably, the sealing cover is provided with an auxiliary water outlet hole.

[0041] By adopting the above solution, when the sealing member descends, the auxiliary water outlet hole can discharge part of the water in the water storage chamber to increase the pressure reduction effect.

[0042] Preferably, the pressure reducing component is integrated with the sealing cover, and a water passage connecting the pressure reducing component and the water storage chamber is provided in the sealing cover.

[0043] The advantage of adopting the above solution in that the pressure reducing member and the sealing cover are provided in one piece is that they are easy to produce and install.

[0044] Preferably, the water storage chamber is arranged in the clean water bucket or the cleaning bucket or between the clean water bucket and the cleaning bucket.

[0045] Preferably, the cleaning bucket and the clean water bucket are integrally provided or separately provided, and the water storage chamber is provided in the cleaning bucket.

[0046] The second purpose of the present invention is to provide a mop bucket, including a sewage bucket, a clean water anti-pollution cleaning bucket is provided on one side of the sewage bucket, a cleaning bucket is located between the clean water bucket and the sewage bucket, and a mouth-squeezing device for squeezing the flat mop head is provided at the mouth of the cleaning bucket.

[0047] By adopting the above solution, after the flat mop is inserted into the cleaning bucket, as the flat mop head descends, the seal can be squeezed to the maximum descending stroke, and after the flat mop head rises, the sewage is squeezed out through the stroking extrusion device and introduced into the sewage bucket. During the entire cleaning cycle of the flat mop head, the water storage chamber is always isolated from the cleaning bucket, avoiding contamination of the water in the clean water bucket.

[0048] Preferably, the sewage bucket and the cleaning bucket or the clean water bucket are integrally arranged or detachably arranged.

[0049] The present invention has significant technical effects due to the adoption of the above technical solutions:

[0050] 1. Add a water storage chamber. There is a seal inside the water storage chamber that is raised and lowered. A matching piece extends from the upper end of the seal to the outside of the water storage chamber. Seepage holes and water outlet holes are set on both sides of the water storage chamber. The water outlet holes are higher than the seepage holes. When the matching piece is squeezed down by the flat mop head until the seal completely blocks the water outlet hole, the cleaning bucket is isolated from the water storage chamber. When the time it takes for the flat mop head to rise and fall once is less than the time it takes for the seal to open the water outlet hole, the seal is always in a state of sealing the water outlet hole during the entire cleaning cycle, thereby preventing water from the water storage chamber from mixing into the cleaning bucket, and ultimately preventing water from mixing into the clean water bucket, thereby ensuring the water quality in the clean water bucket;

[0051] 2. A pressure-reducing mechanism is provided on the seal or the water storage chamber. The pressure-reducing mechanism is a seal that can open or close the drainage hole. The seal is an elastic plug that can be deformed to expose or block the drainage hole, or a sealing ball that is lifted and lowered to open or expose the drainage hole. The pressure-reducing mechanism can quickly discharge the water in the water storage chamber when the flat mop head presses the extension tube so that the seal can be lowered to a sufficient depth. The lowering of the seal can allow the flat mop head to be lowered to a sufficient depth synchronously, ensuring that the flat mop head can be lowered to be completely soaked. At the same time, the time required for the seal to rise and open the water outlet is significantly increased, further improving the performance of isolating the water storage chamber and the cleaning bucket.

[0069] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0070] Example 1

[0071] A mop bucket, see Figure 1-Figure 3As shown, it includes a barrel body and a barrel cover 18. The barrel body includes a sewage barrel 16 and a clean water anti-pollution cleaning barrel arranged on one side of the sewage barrel 16. The clean water anti-pollution cleaning barrel includes an independently arranged clean water barrel 1 and a cleaning barrel 2. The cleaning barrel 2 is located between the clean water barrel 1 and the sewage barrel 16. The clean water barrel 1 and the cleaning barrel 2 are integrated. The sewage barrel 16 and the cleaning barrel 2 are integrated or detachable. In this embodiment, the cleaning barrel 2 and the sewage barrel 16 are detachably arranged by screws. Fasteners 19 are flipped on both sides of the barrel cover 18, and buckle grooves 20 for the fasteners 19 to be simultaneously inserted are provided on the outer walls of the cleaning barrel 2 and the sewage barrel 16.

[0072] A mouth-squeezing device 17 for squeezing the flat mop head 10 is provided at the mouth of the cleaning bucket 2. When the flat mop head 10 is placed in the cleaning bucket 2 and repeatedly raised and lowered, the water on the flat mop head 10 can be squeezed out by the mouth-squeezing device 17 and delivered to the sewage bucket 16. The bucket cover 18 is provided with a water inlet 181 for filling water into the clean water bucket 1, a slot 182 for inserting the flat mop head 10 into the cleaning bucket 2, and an observation port for observing the water level in the sewage bucket 16. A flip cover 183 is hinged on the observation port. The above structure is a prior art.

[0073] The cleaning bucket is provided with a water guide mechanism for guiding the clean water in the clean water bucket 1 into the cleaning bucket 2. Figure 4-Figure 5 As shown, the water guide mechanism includes a water storage chamber 3, which is arranged in the clean water bucket 1 or in the cleaning bucket 2 or between the clean water bucket 1 and the cleaning bucket 2. In this embodiment, the water storage chamber 3 is integrally arranged in the cleaning bucket 2 and the connection between the clean water bucket 1, the water storage chamber 3 and the cleaning bucket 2 shares a side wall. Both sides of the water storage chamber 3 are respectively provided with a seepage hole 4 connected to the clean water bucket 1 and a water outlet hole 5 connected to the cleaning bucket 2. The water outlet hole 5 is higher than the seepage hole 4. A sealing lifting device is provided in the water storage chamber 3, which can completely block the water outlet hole 5 when descending and expose at least part of the water outlet hole 5 after rising. The seal 6 and the water storage chamber 3 are sealed by a sealing ring 7. An annular groove 61 for embedding the sealing ring 7 is provided on the outer wall of the seal 6.

[0074] The lifting and lowering of the sealing member 6 is controlled by the lifting and lowering movement of the flat mop head 10 in the water storage chamber 3. An elastic member 11 is provided in the sealing member 6 to drive the sealing member 6 to be in an ascending state. The elastic member 11 is a spring. The two ends of the spring are elastically abutted against the bottom of the water storage chamber 3 and the sealing member 6 respectively. A matching member 8 is provided at the upper end of the sealing member 6, which passes out of the water storage chamber 3 and elastically abuts against the flat mop head 10 inserted into the cleaning bucket 2. In normal state, the elastic member 11 is in a reset state, and the sealing member 6 is in an ascending state and partially exposes the water outlet 5; when the flat mop head 10 is inserted into the cleaning bucket 2, the hinged block of the flat mop head 10 hinged to the mop rod first abuts against the matching member 8. As the flat mop head 10 continues to descend, the elastic member 11 is compressed and the sealing member 6 descends to block the water outlet 5.

[0075] A pressure reducing mechanism is provided on the upper end of the fitting 8 to quickly guide the water in the water storage chamber 3 to the cleaning barrel 2. The sealing member 6 and the fitting 8 are integrally provided and are in the shape of a barrel with an opening downward. Figure 6-Figure 8 As shown, the pressure reducing mechanism includes a plurality of drainage holes 12 provided at the upper end of the fitting 8 and a sealing member which is lifted and lowered at the upper end of the fitting 8. The sealing member is made of elastic material and is an elastic plug 13. A through hole is provided at the upper end of the fitting 8. The drainage holes 12 are spaced around the hole in a circumferential direction. The elastic plug 13 includes a plug post 131 which is plugged into the through hole, a limit block 133 located at the bottom of the plug post 131 to limit its upward disengagement, and an umbrella-shaped elastic sealing sheet 132 located at the top of the plug post 131. When the seal 6 is lowered, the water storage chamber is under positive pressure, and the edge of the elastic sealing sheet 132 is folded upward to expose all the drainage holes 12. When the seal 6 gradually rises and resets, the water storage chamber is under negative pressure, and the elastic sealing sheet 132 is under negative pressure. The edge of 32 presses downward against the upper end surface of the fitting 8 and thus blocks all the drainage holes 12. The purpose of setting the pressure-reducing mechanism is that before cleaning the flat mop head 10, the water storage chamber 3 is in a state of being filled with water. It is difficult to drain the water quickly by relying solely on the water outlet 5. After the sealing member 6 is lowered to seal the water outlet 5, the sealing member 6 can only drain water outward through the seepage hole and is difficult to continue to lower, resulting in the flat mop head 10 being unable to descend to a sufficient depth to achieve complete soaking. After the pressure-reducing mechanism is set, the outer edge of the elastic plug 13 is folded upward under the action of water pressure to expose the drainage holes 12. The water in the water storage chamber 3 can be continuously discharged through the drainage holes 12, and the sealing member 6 can be lowered to a sufficient depth to ensure that the flat mop head 10 can be completely soaked.

[0076] In order to prevent the flat mop head 10 from pressing the fitting 8 to interfere with the folding of the seal, Figure 9 As shown, an extension tube 9 extends from the upper end of the fitting 8 and abuts against the flat mop head 10. The extension tube 9 is higher than the elastic plug 13. The above arrangement ensures that the deformation of the elastic plug is not disturbed and ensures that the flat mop head 10 can be lowered to a sufficient depth when cleaning the flat mop head 10.

[0077] The water storage chamber 3 is provided with an installation mechanism for facilitating the installation of the sealing member 6 and the elastic member 11. Figure 6 and Figure 8 As shown, the installation mechanism includes a slot 14 opened at the bottom of the water storage chamber 3 for inserting the sealing member 6 and the elastic member 11, and a sealing cover 15 sealed on the slot 14. The sealing cover 15 is detachably locked to the bottom of the water storage chamber 3 by screws.

[0078] The working principle of this embodiment is:

[0079] At normal pressure, the elastic member 11 is in a reset state, the sealing member 6 rises to its maximum stroke, the clean water bucket 1, the water storage chamber 3 and the cleaning bucket 2 are interpenetratingly arranged, and the water in the clean water bucket 1 seeps into the water storage chamber 3 and then into the cleaning bucket 2 until the water level in the cleaning bucket 2 is level with the clean water bucket 1. When the flat mop head 10 is folded to be parallel to the mop rod and inserted into the cleaning bucket 2, the hinge block of the flat mop head 10 abuts against the upper end of the extension tube 9. As the flat mop head 10 further descends, the elastic sealing member 6 is squeezed and raised by the water pressure in the water storage chamber 3, squeezing the water in the water storage chamber 3 into the cleaning bucket 2. Whenever the flat mop plate rises, the flat mop head 10 The water is squeezed into the sewage bucket 16 by the stroking and squeezing device 17. At the same time, since the water seepage speed of the water seepage hole 4 is much lower than one lifting cycle of the flat mop head 10, when the flat mop head 10 drops again, the reset stroke of the seal 6 is insufficient, and the water outlet hole 5 is still in a state of being sealed by the seal 6. Therefore, the water storage chamber 3 and the cleaning bucket 2 are always in an isolated state, thereby preventing the water from the cleaning bucket 2 from entering the water storage chamber 3, and further avoiding the contamination of the clean water in the clean water bucket 1. When the flat mop head 10 is pulled out after cleaning, the seal 6 continues to rise slowly until the water outlet hole 5 is opened. At this time, the clean water in the water storage chamber 3 enters the cleaning bucket 2 again.

[0080] Example 2

[0081] The difference between this embodiment and embodiment 1 is that, referring to Figure 10-11 As shown, the seal is made of an elastic material in one piece, the sealing body is a sealing ball 21, the upper end of the fitting 8 is set to an arc shape that fits the sealing ball 21, more than one drainage hole 12 is set, and a limit member is set on the extension tube 9 to limit the sealing ball 21 from falling out. The limit member is a horizontally set limit pin 22, and a socket 91 for the limit pin 22 to be inserted with interference is set on both side walls of the extension tube 9.

[0082] When the sealing member 6 descends, the pressure in the water storage chamber 3 increases, the sealing ball 21 rises under the action of the water pressure, and the water in the water storage chamber 3 is discharged into the cleaning bucket 2 through the drainage hole 12; when the sealing member 6 is reset, negative pressure is formed in the water storage chamber 3, and the sealing ball 21 is adsorbed on the drainage hole 12, blocking the drainage hole 12.

[0083] Example 3

[0084] The difference between this embodiment and embodiment 2 is that, referring to Figure 12 As shown, the cleaning bucket 2 and the clean water bucket 1 are set separately, the water storage chamber 3 is set in the cleaning bucket 2, the clean water bucket 1 and the sewage bucket 16 are detachably spliced ​​and fixed, and an assembly shell 201 with a built-in splicing device 17 is extended from one side of the cleaning bucket 2. The cleaning bucket 1 is overlapped on the upper end of the splicing surface of the clean water bucket 1 and the sewage bucket 16 through the assembly shell 201, and the drainage outlet of the splicing device 17 is located above the sewage bucket 16.

[0085] Example 4

[0086] The difference between this embodiment and embodiment 3 is that, referring to Figure 13-14 As shown, a pressure reducing member 23 connected to one side of the bottom of the water storage chamber 3 is provided on one side of the water storage chamber 3. The pressure reducing member 23 can be provided in the cleaning bucket 2 or the clean water bucket 1, preferably in the clean water bucket 1. In this embodiment, it is provided in the clean water bucket 1. A drainage hole 12 is provided at the upper end of the pressure reducing member 23, and a sealing body that can open or close the drainage hole is provided on the pressure reducing member 23.

[0087] The sealing body of this embodiment also uses a sealing ball 21. An extension tube 9 extends from the upper end of the pressure reducing member 23. The upper end of the pressure reducing member 23 is set to an arc shape that fits the sealing ball 21. More than one drainage hole 12 is set. A limiting member is set on the extension tube 9 to limit the sealing ball 21 from escaping. The limiting member is a sealing ring plug 24 that is elastically inserted into the extension tube 9 with interference fit. The inner diameter of the sealing ring plug 24 is much smaller than the diameter of the sealing ball 21.

[0088] The pressure reducing member 23 is arranged in the clean water bucket 1. When the flat mop head 10 presses against the fitting member 8 to drive the sealing member 6 to rise and fall in the water storage chamber 3, the water in the water storage chamber 3 is discharged into the clean water bucket 1 without adding extra water in the cleaning bucket 2. This can shorten the cleaning time of the flat mop head 10 and accelerate the drying of the flat mop head 10.

[0089] Example 5

[0090] The difference between this embodiment and embodiment 4 is that, referring to Figure 15-17 As shown, the sealing cover 15 is provided with an auxiliary water outlet 25 , the pressure reducing member 23 is integrally provided with the sealing cover 15 , and a water passage 26 connecting the pressure reducing member 23 and the water storage chamber 3 is provided in the sealing cover 15 .
