Description

Technical Field

[0001] This invention relates to a feminine hygiene device, and more particularly to a feminine hygiene device that is easy to adjust with one hand. Background Technology

[0002] A feminine wash device, also known as a bidet or douche, typically consists of a handle and a nozzle. The handle has an adjustment switch, which is either a rotary switch or a push-button switch. However, neither type of switch is convenient to use. With a rotary switch, the user has to hold the handle with one hand and turn the switch with the other to adjust the water flow. While a push-button switch allows for one-handed operation, adjusting the water flow requires continuous pressing, which can easily cause hand fatigue and result in inconsistent water flow. Neither design is user-friendly.

[0003] In addition, existing feminine hygiene devices only have the function of water intake and output and do not have the function of water purification. This causes suspended solids and impurities in the water to come into direct contact with sensitive parts of the body, resulting in unnecessary infection. Summary of the Invention

[0004] This invention provides a feminine hygiene device, the purpose of which is to overcome the problem of inconvenient operation of existing rotary or push-button switches.

[0005] To achieve the objective, the technical solution provided by this invention is as follows:

[0006] A user-friendly feminine hygiene device includes a handheld part, a nozzle part, and a control valve for adjusting the flow rate. The control valve has a rotatable valve stem with a knob connected to its free end. The knob includes a knob sleeve and a knob handle for easy pushing. The knob sleeve is fixedly installed on the free end of the valve stem, and one end of the knob handle is fixedly connected to the knob sleeve. The orthogonal projection of the knob handle is located on the outer side of the handheld part.

[0007] In the recommended embodiment, the handheld part has a water inlet chamber inside, and the handheld part also includes a partition chamber separated from the water inlet chamber. The partition chamber is close to the nozzle section, and the partition chamber has a water inlet and a water outlet respectively. The water inlet communicates with the water inlet chamber, and the water outlet communicates with the nozzle section. The control valve is sealed and installed in the partition chamber and is used to control the water output of the nozzle section. The water inlet of the partition chamber has a small diameter, usually in the shape of an orifice, which can increase the water output pressure of the nozzle section on the one hand, and on the other hand, it can intercept the flow, so that the water stays in the water inlet chamber for a longer time.

[0008] In the recommended embodiment, based on the usage state, the handle has a water inlet cavity extending in the length direction. The partition chamber includes a partition tube that separates from the water inlet cavity and penetrates the left and right side walls of the handle in the width direction, and a partition plate radially installed inside the partition tube. The partition plate divides the partition tube into a connecting cavity on one side and a valve cavity on the other side. The partition tube is close to the nozzle section. The valve cavity has a water inlet and a water outlet, respectively. The water inlet communicates with the water inlet cavity, and the water outlet communicates with the nozzle section. The control valve is sealed and installed inside the valve cavity and is used to control the water output of the nozzle section. The use of a partition tube penetrating the left and right sides of the handle and a partition plate radially installed inside the partition tube facilitates mold opening and helps reduce production costs.

[0009] In the recommended embodiment, the knob further includes a driven sleeve, with the other end of the knob handle fixedly connected to the driven sleeve; a driven shaft is provided inside the connecting cavity, with one end of the driven shaft fixed to a partition, and the driven sleeve rotatably fitted onto the other end of the driven shaft. The knob simultaneously comprises a knob sleeve, a knob handle, and a driven sleeve, forming an overall "ear" shape. The advantage of this structure is that, regardless of whether the handle is held with the left or right hand, the thumb can easily push the knob handle to rotate, thereby effectively regulating the flow rate.

[0010] In the recommended embodiment, a filter element assembly is provided within the water inlet chamber. This assembly includes a cylindrical filter element, a front end cap with an outlet, and a closed rear end cap. A purified water channel is formed at the center of the filter element. A raised ring is provided on the outer surface of the separator tube, and the water inlet of the valve chamber is located within the raised ring. The front end cap is sealed to the raised ring, and the purified water channel communicates with the water inlet of the valve chamber. The filter element assembly can be a composite filter element assembly or an activated carbon filter element assembly, etc., facilitating complete replacement.

[0011] In the recommended embodiment, the filter element is a silver-impregnated activated carbon filter element. It has high sterilization efficiency, and the silver ions are not easily shed, making it relatively safe to use.

[0012] In the recommended embodiment, the water inlet chamber is provided with a filter element assembly, which includes a perforated front end cover, a perforated rear end cover, and filter media filled between the front and rear end covers. The front end cover and the rear end cover are respectively radially installed in the water inlet chamber, and the outer diameter of the front end cover and the rear end cover is the same as the inner diameter of the water inlet chamber.

[0013] In the recommended embodiment, the water inlet chamber is further provided with a fragrance container and fragrance. The fragrance container is fixedly installed on the inner wall of the water inlet chamber and located at the rear end of the filter element assembly. The fragrance is filled in the fragrance container, and venturi holes are formed on the inner side wall of the fragrance container. Through the venturi holes, the fragrance in the fragrance container will gradually dissolve in the water flow, giving the water a light fragrance, thereby enhancing the user experience.

[0014] In the recommended embodiment, an ultrafiltration assembly is provided in the inlet chamber. The ultrafiltration assembly includes a front cover with an outlet, a filter cartridge, and an ultrafiltration membrane bundle. The front cover is installed at the front end of the filter cartridge, and the outlet end of the ultrafiltration membrane bundle is fixed to the front cover. A raised ring is provided on the outer side of the separator tube, and the inlet of the valve chamber is located inside the raised ring. The front cover is sealed to the raised ring, and the outlet end of the ultrafiltration membrane bundle is connected to the inlet of the valve chamber.

[0015] In the recommended embodiment, the partition chamber includes a partition cylinder that is separated from the water inlet chamber and extends through one side wall of the handheld part in the width direction. The partition cylinder is close to the nozzle part. The partition cylinder is provided with a water inlet and a water outlet. The water inlet is connected to the water inlet chamber, and the water outlet is connected to the nozzle part. The control valve is sealed and installed inside the partition cylinder and is used to control the water output of the nozzle part.

[0016] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0017] This invention greatly optimizes user comfort by changing the structure of the handheld part and the knob, while improving the layout of the control valve and the knob. When in use, hold the handheld part with your palm, place your thumb naturally on the knob handle, and then use your thumb to push the knob handle back and forth to adjust the flow of the feminine hygiene device.

Detailed Implementation

[0037] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. The following embodiments are used to illustrate the invention, but are not intended to limit the scope of the invention.

[0038] Example 1

[0039] Reference Figure 1 and Figure 2 A user-friendly feminine hygiene device, mainly comprising a handheld part 1, an ear-shaped knob 2, a control valve 3, and a nozzle part 4.

[0040] As shown in the figure, taking the usage state as the standard, the handheld part 1 in this embodiment is a long and straight strip. It can be made of metal, plastic, or other known materials. The cross-sectional shape of the handheld part 1 can be designed according to actual needs. In this embodiment, its inner radial cross-section is circular; the outer radial cross-section is composed of four identical arc-shaped surfaces spliced ​​together. This outer surface structure not only feels comfortable but also prevents slippage. The handheld part 1 has a hollow structure. Its rear end is connected to the water inlet pipe (not shown in the figure), and its front end is connected to the nozzle part 4.

[0041] Simultaneously refer to Figure 3 In this embodiment, the handheld part 1 includes a front-end assembly part 12 and a rear-end main body part 11, the length of the main body part 11 being greater than the length of the assembly part 12. (See also...) Figure 2 The main body 11 is roughly hollow and tubular, with the hollow portion forming a first cavity 110. In its operational state, the main body 11 is roughly divided into a one-piece front connecting section 111, a middle main body section 112, and a rear threaded section 113. The rear diameter of the main body section 112 gradually decreases and connects to the threaded section 113, which is used to connect to an external water inlet pipe. The outer diameter of the connecting section 111 is smaller than the outer diameter of the main body section 112, forming a stepped surface 114 between the connecting section 111 and the main body section 112. As shown in the figure, the connecting section 111 has two protruding buckles 115, which are symmetrically arranged centrally. A retaining ring 116 (not shown in the figure) is also provided near the stepped surface 114 for limiting the sealing ring.

[0042] Simultaneously refer to Figure 4 and Figure 5 The assembly part 12 is also a hollow structure. Near the nozzle part 4, the assembly part 12 is provided with a partition tube 13 and a baffle plate 14. The partition tube 13 penetrates the left and right side walls of the assembly part 12 in the width direction. In this embodiment, the central axis of the partition tube 13 is perpendicular to the central axis of both the nozzle part 4 and the handheld part 1. The baffle plate 14 is radially installed inside the partition tube 13 and divides the partition tube 13 into a connecting cavity 15 on one side and a valve cavity 16 on the other side.

[0043] Continue to refer to Figure 4and Figure 5 The rear end of the assembly part 12 is an open end 121. A guide groove 122 is provided on the inner wall of the open end 121. The buckle 115 on the connecting section 111 cooperates with the guide groove 122. During installation, the connecting section 111 is inserted into the open end 121 of the assembly part 12, and the main body 11 and the assembly part 12 are rotated relative to each other. At this time, the buckle 115 is locked in the guide groove 122, thus completing the assembly of the handle 1. Of course, the connection method between the assembly part 12 and the main body 11 is not limited to this. The two can also be connected in a spiral or other way to achieve a detachable connection, as long as the liquid seal requirement is met.

[0044] Simultaneously refer to Figure 6 The assembly part 12 is also a hollow structure. Excluding the internal space occupied by the partition tube 13, the remaining internal space of the assembly part 12 forms a second cavity 120. The second cavity 120 and the first cavity 110 of the main body 11 together form a complete water inlet cavity 5. The water inlet cavity 5 extends along the length of the handheld part 1. The partition tube 13 is separated from the water inlet cavity 5. The valve chamber 16 of the partition tube 13 has an inlet 161 and an outlet 162. The inlet 161 communicates with the second cavity 120 of the water inlet cavity 5, and the outlet 162 communicates with the core tube 41 of the nozzle part 4. The control valve 3 (the structure of the control valve is not limited, as long as it has a rotatable valve stem) is sealed and installed inside the valve chamber 16, such as... Figure 2 As shown, control valve 3 is inserted into valve chamber 16. (See also...) Figure 7 The left end of control valve 3 is the inlet end 31, which connects to the inlet port 161 of valve chamber 16; the outlet end 32 of control valve 3 is located on the outer surface and connects to the outlet port 162 of valve chamber 16. Valve chamber 16 has a threaded sealing structure near the port, and the right end of control valve 3 also has a threaded structure adapted to the above structure to achieve mutual sealing. After installation, the valve stem 33 of control valve 3 is perpendicular to the axis of the handle 1, and the free end of valve stem 33 protrudes from the outer surface of handle 1. In use, rotating knob 2 rotates valve stem 33 to control the water output of nozzle 4.

[0045] like Figure 5 As shown, the connecting cavity 15 is provided with a hollow driven shaft 151. One end of the driven shaft 151 is fixed to the partition 14, and the driven shaft 151 and the valve stem 33 are located on the same axis, or at least parallel.

[0046] Simultaneously refer to Figure 8A knob 2 is connected to the free end of the valve stem 33. The knob 2 includes a circular knob sleeve 21, a circular driven sleeve 22, and a knob handle 23 for easy thumb pushing. Both the knob sleeve 21 and the driven sleeve 22 have connecting holes in their centers. For aesthetic purposes, in practical applications, a cap 24 is usually added to the knob sleeve 21 and the driven sleeve 22. The knob sleeve 21 is fixedly installed on the free end of the valve stem 33. In this embodiment, the two are fastened together by vertical grooves. Of course, other detachable connection methods can also be used for installation, as long as synchronous movement is ensured. The knob sleeve 21 rotates synchronously with the valve stem 33, and the driven sleeve 22 is rotatably fitted onto the free end of the driven shaft 151. The knob handle 23 is roughly arc-shaped. One end of the knob handle 23 is fixedly connected to the knob sleeve 21, and the other end is fixedly connected to the driven sleeve 22. In this embodiment, all parts of the knob 2 are integrally formed, and the orthographic projection of the knob handle 23 is located on the outer side of the handheld part 1. In order to make it easier for the thumb to adjust the knob 2, the thumb contact area of ​​the knob handle 23 gradually expands from the middle to both ends. As can be seen from the figure, the knob handle 23 at both ends is roughly triangular.

[0047] Continue to refer to Figure 2 , Figure 6 and Figure 9 The water inlet chamber 5 is equipped with a filter element assembly. In this embodiment, the filter element assembly is a pleated filter element assembly 6 made of microporous material. The pleated filter element assembly 6 includes a front cover 61, a rear cover 62, and a hollow cylindrical pleated filter element 63. The front cover 61 has a water outlet, the rear cover 62 is a closed structure, and a water collection pipe 60 (purified water channel) is formed in the center of the pleated filter element 63. One end of the pleated filter element 63 is connected to the front cover 61, and the other end is connected to the rear cover 62. The pleated filter element 63 in this embodiment can be selected as needed; it can be a single-layer structure of a single material or a multi-layer composite structure composed of multiple materials.

[0048] As shown in the figure, the pleated filter element assembly 6 extends along the length of the water inlet chamber 5 (handheld part); a raised ring 131 is provided on the outer side of the separator tube 13, and the water inlet 161 of the valve chamber 16 is located inside the raised ring 131; the front end cap 61 of the pleated filter element 6 is sealed to the raised ring 131, and the water collection pipe 60 of the pleated filter element 6 is connected to the water inlet 161 of the valve chamber 16. During operation, water flows into the water inlet chamber 5 from the external water inlet pipe, and the water in the water inlet chamber 5 enters the water collection pipe 60 from the pleated filter element 63, then enters the valve chamber 16 from the water collection pipe 60, and finally flows into the spray nozzle 4 from the valve chamber 16 and is sprayed out from the spray nozzle 4.

[0049] The nozzle section 4 is mounted at an angle to the handheld part 1, and the included angle between the nozzle section 4 and the handheld part 1 is 135°.

[0050] Simultaneously refer to Figure 6 and Figure 10The nozzle section 4 includes a core tube 41, an outer tube 42, and a nozzle 43. The water inlet end of the core tube 41 is integrally formed and connected to the assembly section 12, and the water inlet end of the core tube 41 communicates with the water outlet 162 of the valve chamber 16. As shown in the figure, the free end of the core tube 41 forms a beveled port 410, the area of ​​which is larger than the radial cross-sectional area of ​​the core tube 41. The core tube 41 also has an arc-shaped groove 411 and two annular grooves 412 for installing sealing rings (not shown in the figure). The two annular grooves 412 are close to the beveled port 410, and the plane of the arc-shaped groove 411 is parallel to the beveled port 410 and lies between the annular grooves 412 and the beveled port 410.

[0051] The outer sleeve 42 is fitted onto the core tube 41. In its operational state, the outer sleeve 42 includes a rear sleeve 421 and a front sleeve 422. The rear sleeve 421 is integrally formed and connected to the assembly part 12. The front sleeve 422 is detachably installed on the rear sleeve 421. The front sleeve 422 includes an integrally formed straight section 423 and a bent section 424. The straight section 423 cooperates with the rear sleeve 421 to fit the core tube 41 inside it. In this embodiment, the inner cross-sections of the straight section 423 and the rear sleeve 421 are circular, and their outer cross-sections are identical and both elliptical. The cross-section of the bent section 424 is circular, and the nozzle 43 is installed at the port of the bent section 424. A sealing ring (not shown in the figure) is fitted into the corresponding annular groove 412 to form a liquid seal between the mandrel 41 and the outer sleeve 42. Meanwhile, in order to prevent the front sleeve 422 and the rear sleeve 421 from moving axially, two symmetrical axial grooves 425 are provided on the inner wall of the bent section 424. The axial grooves 425 correspond to the arc-shaped slots 411 mentioned above. During installation, a snap-fit ​​piece 44 is inserted into the arc-shaped slots 411 and the axial grooves 425 at the same time to axially position the front sleeve 422.

[0052] Reference Figure 11 and Figure 12This embodiment also discloses a mounting base 7 for the feminine hygiene device, which is fixed to a wall. The mounting base includes a base plate 71 and a retaining seat 72. The retaining seat 72 is fixed to the base plate 71 and includes clamps 73 on the left and right sides and a retaining channel in the middle. The clamps 73 on the left and right sides are streamlined curved surfaces and are symmetrically arranged on the left and right sides of the retaining channel. The retaining channel includes a vertical section 74 at the upper end and a base support section 75 at the lower end. The upper end of the vertical section 74 is open, and the lower end is connected to the base support section 75. The size and shape of the vertical section 74 are adapted to the corresponding part of the handle part 1 (main body part 11). During installation, the vertical section 74 partially surrounds the handle part 1 to position the handle part 1 in the forward and backward directions, preventing the handle part 1 from tilting forward and falling off the mounting base 7. The base section 75 is approximately spherical, and its shape matches the rear end of the main body section 112. It is used to position the handle 1 vertically, preventing it from slipping off the lower end of the mounting base 7. As shown in the figure, the mounting base 7 is fixed to a wall or fixed surface, and the feminine hygiene device is placed inside the mounting base 7. Specifically, the main body section 112 of the handle 1 cooperates with the mounting base 7. In use, simply pull up the feminine hygiene device and remove it from the upper end of the mounting base 7. This combination not only makes it convenient to use, but the optimized mounting base 7 also coordinates seamlessly with the feminine hygiene device, providing the user with a comfortable visual experience and a good user experience.

[0053] Example 2

[0054] Reference Figure 13 This embodiment is basically the same as the structure of the first embodiment, except that the filter element assembly is a silver-loaded activated carbon filter element assembly 6a. The silver-loaded activated carbon filter element assembly 6a includes a front cover 61a, a rear cover 62a, and a hollow cylindrical silver-loaded activated carbon filter element 63a. The front cover 61a is provided with a water outlet, the rear cover 62a is a closed structure, and a water collection pipe 60a (purified water channel) is formed in the center of the silver-loaded activated carbon filter element 63a. One end of the silver-loaded activated carbon filter element 63a is connected to the front cover 61a, and the other end is connected to the rear cover 62a.

[0055] In this embodiment, the silver-loaded activated carbon filter element is treated with the inventor's unique process, which not only significantly improves sterilization efficiency but also solves the problem of silver shedding during water treatment.

[0056] The specific production process of silver-impregnated activated carbon filter elements is as follows:

[0057] a. Crushing: Crush the coconut shell activated carbon and sieve it through a 20-30 mesh screen; crush the PE binder and sieve it through a 200-250 mesh screen.

[0058] b. Soaking: The pulverized coconut shell activated carbon is soaked in a silver ammonia complex solution with a silver ion concentration of 0.7% until fully soaked;

[0059] c. Filtration and centrifugation: Filter and separate the coconut shell activated carbon from the silver ammonia complex solution in step b. Then, put the coconut shell activated carbon into a centrifuge and centrifuge it clockwise at a high speed of 6000 r / min to 8000 r / min. Then, centrifuge it counterclockwise at a high speed of 6000 r / min to 8000 r / min.

[0060] d. Rinsing and drying: First, neutralize the coconut shell activated carbon in step c with a weak alkali to bring its pH value to 7-7.2. Then, rinse the coconut shell activated carbon with ultrafiltration water and put the rinsed coconut shell activated carbon into a drying oven to dry.

[0061] e. Stir and mix: Take the coconut shell activated carbon from step d, the PE binder from step a, and a small amount of ultrafiltration water, stir and mix the three together evenly, wherein the weight parts of coconut shell activated carbon are 80-90 parts, the weight parts of PE binder are 5-10 parts, and the weight parts of ultrafiltration water are 5-10 parts.

[0062] f. Sintering: The well-stirred PE binder, coconut shell activated carbon, and a small amount of ultrafiltration water are filled into the mold and compacted. The hollow cylindrical silver-loaded activated carbon filter element of this embodiment is produced by sintering at a temperature of 200℃-230℃.

[0063] The table below shows the comparative experimental data of silver-loaded activated carbon filter cartridges.

[0064]

[0065] As can be seen from the table above, when using the silver-loaded activated carbon filter cartridge described in this invention to filter tap water, the vast majority of Escherichia coli and Staphylococcus aureus are removed. Moreover, after a period of use, the levels of Staphylococcus aureus and Escherichia coli remain below 100 CFU / plate. This demonstrates that the silver-loaded activated carbon filter cartridge, with its antibacterial and bacteriostatic effects, remains highly effective when used in tap water systems after a period of time (typically after processing 5 tons of water).

[0066] In addition, the silver-loaded activated carbon filter element of the present invention, after soaking, has a maximum silver ion precipitation of 13.2 ug / L, which is far lower than the national standard of 50 ug / L.

[0067] Example 3

[0068] Reference Figure 14This third embodiment is basically the same in structure as the first embodiment described above. The main difference is that in this embodiment, the filter element assembly includes a perforated front cover 61b, a perforated rear cover 62b, and filter media 63b (calcium sulfite) filled between the front and rear covers 61b and 62b. The front cover 61b and the rear cover 62b are radially installed in the water inlet chamber 5, and the outer diameter of the front cover 61b and the rear cover 62b is the same as the inner diameter of the water inlet chamber 5. In this embodiment, the filter media 63b is calcium sulfite, but any other known existing filter material can be used instead, or a combination of multiple materials can be used. During operation, the water in the water inlet chamber 5 passes through the rear cover 62b, the filter media 63b, and the front cover 61b in sequence, and is discharged after being fully filtered by the filter media 63b.

[0069] In addition, in this third embodiment, a circular fragrance container 64b is also provided inside the water inlet chamber 5. This fragrance container 64b is fixedly and sealed to the inner wall of the water inlet chamber 5 and is located at the rear end of the filter element assembly. Figure 14 As can be seen, a Venturi orifice 65b is provided on the lower part of the inner wall of the spice container 64b, and the spice container 64b is filled with a semi-rigid solid gel-like green natural spice 66b. During use, water flows through the Venturi orifice, comes into contact with the green natural spice 66b, and gradually dissolves it, giving the water a faint osmanthus fragrance. The preparation process of the aforementioned green natural spice is as follows:

[0070] A. Collect fresh osmanthus flowers, wash and crush them, and add water to the crushed fresh osmanthus flowers at a weight ratio of 1:1.2-1.5. Cook the mixture under a pressure of 70KPa-80KPa for 30-35 minutes. After cooling and filtering, obtain the cooking liquid.

[0071] B. Add water-soluble pectin, konjac powder and preservative to the cooking liquid in step A. The weight ratio of the components is 100 parts cooking liquid, 5-8 parts water-soluble pectin, 15-20 parts konjac powder and 0.2-0.3 parts preservative. Gradually heat and continuously stir until it becomes viscous. After cooling, a semi-rigid solid gel-like green natural fragrance is obtained.

[0072] The osmanthus mentioned above is preferably golden osmanthus, as the green, pure natural fragrance made from golden osmanthus has the strongest aroma.

[0073] Example 4

[0074] Reference Figure 15This fourth embodiment is basically the same in structure as the first embodiment above. The main difference is that in this embodiment, an ultrafiltration assembly is provided in the water inlet chamber 5.
